TESTING

TEST EQUIPMENT

 

To determine the water content in lubricating oil or fuel z. B. on board a ship, Martechnic ® has developed portable measuring devices. These make it possible to examine the oil on site, independently of a laboratory. The measured values ​​of the equipment are not as accurate as laboratory values, but they complement them.

The test equipment can be used to monitor the oil status of the machine and, if necessary, to make decisions as to whether maintenance measures need to be carried out.

The test devices are supplied in a handy case that contains all the utensils needed to carry out the test.

WIO CHECK

Water in oil measuring device

 

The water content in oil is an important indicator for the assessment of the engine condition and the performance of a system in general. The WIO CHECK helps to measure these oil parameters on site and in the process of trend monitoring in order to receive regular information about changes in the oil condition.

 FEATURES

  • Measuring range: 0 - 0.4 or 0 - 1.0 vol. % H 2 O

  • Measuring time: up to 20 minutes

  • Tolerance: +/- 3%

 ADVANTAGES

  • Readable in vol. % Water

  • Only one reagent needed

  • Applicable to all mineral oils

  • Easy to use even for untrained personnel

  • Handy to handle and transport

The two chambers of the device are filled with the oil sample and the reagent. The measuring process takes place by shaking the device from time to time and can be ended as soon as the result is constant over 1-2 minutes. It is therefore possible to determine the exact end of the actual reaction.

TWIN CHECK 4.0

TWIN CHECK: NEW, IMPROVED DESIGN IN HARMONY WITH THE 4.0 CONCEPT

 

Electronic water-in-oil / BN test device

An improved and updated version of the TWIN CHECK test device has been developed by Martechnic® to provide the advantages of digitization in a customer-friendly manner. Modularity in the design of the TWIN CHECK 4.0 is a new configuration not previously available on the market.

Each individual component (inserted and screwed) can be replaced in the event of a malfunction or damage. The visible advantages of the innovative technical solution are the most economical on-site diagnosis and the replacement of components without the need to buy a new test device or to pay high costs for diagnosis and repairs on the company premises.

Other important features of the TWIN CHECK 4.0 include the optimization of water-in-oil / BN measurements, an easy-to-use navigation system, automatic data recording and storage as well as the USB-to-serial connection (a terminal program) for data transmission and trend analysis of the condition of lubricating and hydraulic oil.

 FEATURES

  • Measurable parameters

  • Water in oil: none

  • Measuring range: 0 - 1.0 vol. % H 2 O

  • Measuring time: depending on the measured value (min. 2 - max. 20 min.)

  • Tolerance: +/- 3%

  • Base number:

  • Measuring range: 0 - 100 BN

  • Measuring time: depending on the measured value (min. 2 - max. 20 min.)

  • Tolerance: +/- 1 BN

  • Also available as a single test device: water-in-oil or BN

 

 ADVANTAGES

  • Applicable to all mineral oils

  • Improved design with a simple navigation menu for high measurement accuracy

  • Internal memory chip with an average data storage of 2.5 years

  • Digital display of test results

  • USB to serial cable connection for data transmission and trend analysis

  • Determining the base number: 6 storage spaces for up to 6 different oil types from different engines

  • Maintenance and repairs are possible on board

 

The identical measuring procedure of water-in-oil and BN starts as soon as the two chambers of the TWIN CHECK reaction housing have been filled with the oil sample and the reagent and the built-in pressure sensor has accepted the ambient pressure (outlet pressure) as the internal pressure with a zero reference point. The chemical reaction proceeds by shaking the device every two minutes for 15 seconds.

The measurement ends automatically as soon as the determined concentration of water / BN parameter is constant, and the end result is immediately shown on the digital display. Therefore, the measuring time depends directly on the measured value and can vary from 2 to a maximum of 20 minutes.

A single calibration per oil type is required to determine the number of bases.

MT TEST KIT VERIFIER

Compressed air tester

 

Compliance with the essential safety measures on board a ship in accordance with the ISM Code not only helps to ensure the safe operation of ships, but also makes a valuable contribution to marine environmental protection. Following the guidelines set out in Section 10.3 Part A of the ISM Code, namely the need for "... regular checks for the functionality of devices and equipment and technical equipment that are not in constant use ...", Martechnic® developed the MT TEST KIT VERIFIER. The device enables a quick check of the functionality and accuracy of the measurements of the portable test devices based on the gas pressure measurement: WIO CHECK and TWIN CHECK 4.0.

 FEATURES

  • Two options to choose from:

    • Option I: usable test device installed including 0.5 m 4x6 hose

    • Option II: usable test device installed including 0.5 m 4x6 hose with pressure reducer and adapted pressure gauge for direct reading of the water value

  • Tolerance:

    • +/- 0.05% H₂O of the TWIN CHECK 4.0 / WIO CHECK

    • +/- 1 BN of the TWIN CHECK 4.0

 ADVANTAGES

  • The test unit is equipped with a 1 bar safety valve.

  • Avoid setting the pressure too high, which exceeds the max. Reading goes out

  • Functional test by the user possible before the measurement

 

To check the condition of portable test devices (for example, TWIN CHECK 4.0), the "upper" part of the device (the measuring unit with the pressure sensor / manometer) is screwed onto the MT TEST KIT VERIFIER and then either with the calibration pump (if available on site) ) or with the pressure reducer and adapted pressure gauge (can be ordered as a complete version). The prepared unit is then subjected to the test pressure to determine whether the pressure sensor correctly indicates the chemically generated internal pressure. This can be done with the help of two reference pressures that can be set on the manometer (for example 0.3 and 0.6 vol.% H₂O). Regular tests with the MT TEST KIT VERIFIER help the tightness,

WA-SOL®

Water-in-oil test reagent kit

 

Martechnic ® has been using the water-in-oil test reagent kit WA-SOL ® for many years to ensure efficient and economical delivery options. The decisive advantage of the product is in terms of transport, because WA-SOL ® IS NOT CLASSIFIED AS DANGEROUS FOR TRANSPORT and can be delivered without restrictions.

A WA-SOL ® TEST REAGENT KIT CONTAINS:

  • A bottle of “WA-SOL ® Basic”

  • A bottle of “WA-SOL ® Activator”

  • A hook

  • MSDB and instruction manual

* The components are not available individually, but only as a "test reagent kit"

 

For a safe and easy transport, the reaction substance of WA-SOL ® Basic is specially protected to prevent possible contact with water. Before the test procedure, two components WA-SOL ® Basic and WA-SOL ® Activator must be mixed thoroughly on site in a ratio of 1: 1.

COMPA DENS CHECK

Density, compatibility and stability determination - triple test

 

Regular monitoring of the density of the oil supplied enables the conformity of the oil quality and its costs to be confirmed. Checking the stability / compatibility of various heavy oils is important for normal continuous operation of the engine system. In a simple and quick test procedure, these important oil properties can be determined on site using the COMPA DENS CHECK test device.

 FEATURES

  • Density:

  • Measuring range: 0.82 - 1.05 g / ml

  • Measuring time: approx. 2 minutes

  • Oil sample: 120 ml

  • Accurate and reliable analyzes

  • Four different hydrometers with automatically converted density values ​​from 50 ˚C to 15 ˚C

  • Directly visible compatibility / incompatibility of the test results

  • Easy to use even for untrained personnel

 

To measure density, it is necessary to fill the glass tube with the oil sample and place it in the heating bath. As soon as the temperature of 50 ° C is reached, the density can be determined using the appropriate hydrometer. The density value is automatically converted to the standard temperature of 15 ° C. The stability and compatibility of heavy oils are measured with identical test procedures. Two mixed oil samples (or just one sample for stability determination) are heated to 95 ° C in the heating bath. A drop of the warmed oil is applied to the chromotography paper and evaluated as soon as it has dried out.
The COMPA DENS test method used follows ASTM D 4740-04 (2014).

SALT CHECK

Salt / fresh water determination test kit

 

Lubricating oil and fuel can be contaminated with water of different types (fresh or salty). By analyzing the type of water using the SALT / FRESHWATER CHECK, the possible origin of the leak is quickly determined on site.

 FEATURES

  • Measuring range: go / no go

  • Measuring time: approx. 10 minutes

 ADVANTAGES

  • Fast result

  • Only one reagent needed

  • Easy to use even for untrained personnel

A few drops of the separated test liquid W are placed on the perforated indicator plate. If the plate changes color after a few minutes, there is salt in the water. In addition, after a certain experience with this test method, it is possible to approximate the salt contamination in vol. % determine.

MT ON CHECK

Acid number titration test

 

The quality of hydraulic oils can be determined by measuring the acid number and thus determining the level of contamination that can occur in the process of operating the hydraulic system. Since the high acid value can have negative consequences for machine parts, the regular measurement of its level with the help of the MT AN CHECK makes it easy to monitor this oil property on site and to determine the need for an oil change at the right time.

 FEATURES

  • Measuring range: 0 - 3 AN

  • Measuring time: approx. 3 min.

  • Tolerance: +/- 0.1 AN

 ADVANTAGES

  • Simple and quick test procedure

  • Applicable for hydraulic, gear and turbine oils

  • Demonstrative test results

Two reagents (the indicator and the titration liquid) are mixed until a green color develops. The oil sample is added, and when the color of the mixed liquid changes to red, it means that the oil contains acid. The titration liquid is then added dropwise until the resulting mixture changes color to green. The acid number is determined by the amount of titration liquid used and can be determined according to a comparison table.

SPOT CHECK

Pollution rapid test

 

During engine operation, lubricating oils can be contaminated with various substances and primarily with the soot. The SPOT CHECK test method makes it possible to identify a trend in oil quality and thus regularly compare the spot samples received and the corresponding level of oil pollution.

 FEATURES

  • Measuring range: all lubricating oils

  • Measuring time: approx. 1 min.

 ADVANTAGES

  • Easy and quick to use

  • Inexpensive test analysis

  • No chemicals needed

  • Effective in use

An oil drop is applied to the drop sample paper. The oil flows through the chromatography paper and forms a dot. As soon as the dot has dried out, it is ready for analysis. It is possible to determine the following:

  • • The level of soot pollution

  • • The dilution with fuel

  • • Remaining cleaning and dispersing power of the lubricating oil

POLLUTION TEST

Visual particle determination

 

Insoluble particles can be very harmful to the components of the engine systems, especially if they are present in excessive amounts in lubricating and hydraulic oils. The POLLUTION TEST enables regular oil quality monitoring to determine insoluble particles. This allows you to quickly and easily assess the condition of the machine components and efficiently track the changes that occur.

 FEATURES

  • Measuring range:> 3 µm

  • Measuring time: approx. 15 minutes

  • Application: lubricating and hydraulic oil

 ADVANTAGES

  • Direct visual particle evaluation

  • Effective determination of the source of the oil pollution

  • Early detection of wear

  • Helpful for efficient maintenance of machine components

  • Easy to use even for untrained personnel

The oil sample is filtered using the vacuum filtration device and insoluble particles remain in the form of a deposit on the surface of the membrane filter. Then the relative amount, size, shape and type of these particles can be assessed visually immediately. This provides direct information about the quality of the corresponding oil.

FLASH POINT CHECK

Closed crucible / Pensky-Martens method

 

The flash point is an important feature for assessing the oil condition on delivery and the oil used in engine operation. If the flash point is not in its standard ranges and is significantly higher or lower, it may indicate oil thinning and pose a potential hazard. In this regard, the FLASH POINT CHECK helps to determine the flash point of oil directly on site in order to identify potentially dangerous liquids in good time.

 FEATURES

  • Measuring range: 25 - 200 ° C

  • Measuring time: approx. 15 minutes

  • Tolerance: +/- 2% <100 ° C +/- 6 ° C> 100 ° C

  • Tried and tested in the field by the German Navy

 

The test procedure is carried out in the closed crucible test device. The container is filled with the oil sample and heated to the temperature required for gas ignition. The corresponding temperature on the thermometer shows the flash point of the oil.

VISCO DENS PLUS

Test device for measuring viscosity and density

 

A regular check of the viscosity of lubricating and hydraulic oils provides the necessary assurance that the performance of the engine system is stable and efficient. In addition, the determination of the density enables a more precise measurement of the viscosity. Therefore, the VISCO DENS PLUS helps to assess the two oil parameters in a quick test procedure at three different temperatures (40 ˚C, 50 ˚C and 80 ˚C) directly on site.

 FEATURES

  • Measuring range viscosity: 1 - 999 mm² / s

  • Density measuring range: 0.82 - 1.05 g / ml

  • Three different temperatures applicable

  • Four different hydrometers with automatically converted density values ​​to 15 ˚C

 

First, the density of the preheated oil sample is measured using the appropriate hydrometer. The density value is automatically converted to the standard temperature of 15 ° C. Based on the density value obtained and using the falling ball principle, the viscosity value of the same oil sample can be determined. Depending on the viscosity range and the corresponding temperature of the oil sample, two balls with different sizes can be used.

VISCO CYLINDER

Electronic ball drop viscometer

 

The regular monitoring of the oil viscosity and the storage of the data obtained make it possible to carry out an accurate assessment of the trends in the oil condition in order to ensure that the engine system functions continuously and efficiently. The VISCO CYLINDER with its two versions (STANDARD and LOW VIS) measures the viscosity of lubricating and hydraulic oils, and gas oils that have a very low viscosity value, and delivers precise results thanks to the built-in sensors.

  • Tolerance: +/- 3%

 ADVANTAGES

  • Precise sensors for fall time measurement

  • Fast and accurate test results

  • Two versions of the device for different oil types

  • No additional chemicals needed

  • Easy to use even for untrained personnel

 

The viscosity is measured using the ball drop principle and is directly related to the time it takes a metal ball to fall through the oil-filled tube and reach the bottom of the device. The viscosity value can then be assessed.

JUNG CHECK

Falling ball viscometer

 

The viscosity of lubricating and hydraulic oils should be checked at regular intervals because this specific property of the oil is essential for the effective lubricity of the engine system. The JUNG CHECK device measures the viscosity of the oil sample using the ball drop principle. This fast test method delivers precise results and enables an effective assessment of the oil quality to be carried out on site.

 FEATURES

VISCOSITY COMPARISON TEST

Viscosity comparison device

 

The simple test method with the VISCOSITY COMPARISON has been developed to assess a critical physical property of lubricating and hydraulic oils, namely the viscosity. The device provides visually visible information almost immediately and on-site whether the viscosity of the oil sample is still within the tolerance range or not.

 FEATURES

  • Measuring range: lubricating oil

  • Measuring time: approx. 3 min.

 ADVANTAGES

  • No chemicals needed

  • Can be used quickly

  • Immediate evaluation of the test results

  • Easy to use even for untrained personnel

 

Two oil samples of the same temperature (fresh oil sample and sample of the used oil) are compared in the VISCOSITY COMPARISON. Depending on the difference in the flow behavior of the oil samples and by determining the end position of each sample, the viscosity of the used oil can be determined on the "go / no go" principle.

IRON CHECK E

Digital test for the chemical determination of iron content (patent number: 2982974)

 

The iron concentration in the cylinder wiping oil provides information about the wear condition of the engine. Changes in the operation of the two-stroke diesel engines (lower operating temperatures) can lead to the phenomenon of low temperature corrosion (NTK), in particular the corrosion of the cylinder components. The portable test equipment EISENTEST makes it possible to carry out regular analyzes based on a chemical determination of the iron content (corrosive and / or abrasive) in the cylinder wiper oil in order to determine the changes occurring in engine wear directly on site. This enables efficient engine lubrication settings to be made.

 FEATURES

  • Measuring range: 15/20 - 1100 mg / kg (ppm)

  • Measuring temperature: 70 ˚C

  • Measuring time: approx. 15 minutes for two cylinder oil samples

  • Measuring method: Chrominance measuring device with the LED transmitted light

  • Tolerance: +/- 20 mg / kg (ppm) (good repeatability of test results)

 ADVANTAGES

  • Precise, digital, semi-automatic measurement of the iron content

  • Simultaneous processing of two samples (effective and time-saving method)

  • No need to use a color comparison chart

  • Early warning about corrosion problems with regular use

  • Efficient adjustment of the lubrication of crosshead motors

 

The IRON CHECK E test device similarly enables the measurement of all and corroded iron. After quickly preparing the special reaction solution in the glass vials and preheating the glass vials in two chambers A and B of the IRON CHECK E, the oil sample selected for testing can be added to start the digital test analysis. During the chemical reaction of iron in the cylinder wiping oil and a special reaction solution, the color of the derived liquid in the glass vials is automatically evaluated using the built-in chrominance measuring device with the LED transmitted light. The color can vary from light blue to dark blue and it depends directly on the iron concentration in the cylinder oil samples. The darker the color of the liquid, the higher the level of iron concentration that the cylinder lubricant contains. The measured values ​​are then automatically saved in the internal memory.

MT CAT FINES CHECK

Cat Fines determination test for Al and Si based Cat Fines

 

Catalyst fines can be found in heavy oil and these particles can severely impair the functionality of ship engine parts. The MT CAT FINES CHECK test device helps to assess the quality of the heavy oil, ie it can be determined on site whether the abrasive particles are present in the heavy oil or not. This simple and fast test method enables regular testing of heavy oil samples before and after a separator and before the oil is used for engine operation.

 FEATURES

  • Measuring time: up to 15 minutes

  • Up to 8 simultaneous measurements possible

  • Visually quantifiable

 

 ADVANTAGES

  • Simple and quick test method

  • Applicable to all types of heavy oil

The heavy oil samples are prepared using the relevant reagents, then filled into the plastic microcentrifuge tubes and the tubes are placed in parallel in the centrifuge. If the number of microcentrifuge tubes is odd, a filled plastic tube must be used to balance the centrifuge. After taking the heavy oil samples, the concentration of cat fines in the heavy oil can be assessed directly before and after a separator. Using the comparison table (part of every test case MT CAT FINES CHECK) it is possible to quantify the cat fines visually. This means that the quality of the heavy oil supplied and the functionality of the separators can be checked regularly.

POUR POINT CHECK

Pour point measurement

 

With regard to heavy oil and its viscosity value, it is important to determine a sufficiently high temperature for safe oil storage and to operate the engine system. The STOCKPUNKT CHECK test method makes it possible to determine the lowest temperature of the oil sample at which the oil solidifies. You can monitor the correct flowability of the heavy oil directly on site and on a regular basis.

 FEATURES

  • Measuring range: - 20 ° C up to + 30 ° C

  • Measuring time: approx. 10 minutes

  • Tolerance: +/- 2 ° C

 ADVANTAGES

  • Applicable to all heavy oils

  • Simple and quick test method

  • Temperature can be read directly in ° C

  • Easy to use even for untrained personnel

First, a warm oil sample is cooled using the cold spray until the oil stops flowing. The corresponding temperature is noted as temperature A. Then the sample is gradually warmed until the oil flows again. The corresponding temperature is marked as temperature B. The average of both temperatures is the pour point of the oil sample.
