Regular analysis of the amount of metal abrasion in lubricants protects against impending damage to machines in good time. The iron content is of particular importance. His concentration is used to assess the wear and tear of the tested machines. This is particularly important when testing the cylinder wiper oil of 2-stroke marine engines. CM Technologies offers various solutions for on-site iron testing as well as application specific test kits.

IR Analyser

IR spectroscopy is a powerful technique for measuring the concentration of organic molecules. The physical effect of infrared light absorption by molecules contained in the sample is being measured. Each molecule absorbs light of a certain wavelength. The intensity of the absorption is a measure of the concentration of the particular molecule.

During the life cycle of an oil, different decomposition and conversion processes occur at the molecular level. A drop of oil acts as an information memory for both equipment and oil condition, which can be decrypted by IR spectroscopy.

Three interacting mechanisms together form the process of oil aging:

  • Base oil degradation can be used without any training

  • Additive depletion

  • Contamination

Water in Oil

Water in the oil can cause different problems depending on the type of lubricating oil, with corrosion always being a direct effect. Regardless of the application, water displaces the oil on the lubricating surfaces of components, reducing optimal lubrication. In addition, chemical reactions are caused on the lubricating surfaces and other surfaces of components, which accelerates oil aging. Water in lubricating oil is one of the most dangerous "contaminants" in oil because it has a high potential for failure. In oil tanks, water can lead to the growth of microbes, i.e. the formation of yeasts, mold and bacteria, which clog the filter systems and allow fuel systems to corrode quickly.

  • Multiple ranges for exact readings

  • Multilingual software

  • No hazardous reagents needed

Base Number

Measuring the alkaline reserve in engine oils is important to maintain the ability of the lubricant to neutralize acids resulting from combustion.

To avoid acid corrosion inside a combustion engine, it is essential to maintain a certain alkalinity reserve. Additives (mostly calcium) are added to the oil to neutralize any acid which might build up during the combustion process.

Viscosity/Density Meter

CMT's Viscosity/Density Meter combines two very important parameters for condition monitoring. The device guides you through the procedure and gives you fast results with high accuracy.

Viscosity and density testing is important in any aspect of marine or industry. The efficiency of any engine depends on the correct viscosity of the fuel.
Viscosity is very important to keep the machine's lubricating oil film in place. Lubrication, in turn, is very important to avoid metallic contact, abrasion, microwelding and wear of the sliding surfaces.


The CMT Viscotube is a falling ball viscosimeter allowing to measure the viscosity of oil in centistokes on-site.

The Viscotube closes the gap between the low cost viscosity stick and the highly accurate Heated Viscosity Meter


In general, fuels are produced as stably as possible - i.e. fuels should not show any tendency to form asphaltic sludge. This does not necessarily mean that two fuels that are stable in themselves are also compatible, i.e. stable, in a mixture. A fuel mixture is considered to be stable if it is homogeneous immediately after being combined, remains homogeneous under normal storage conditions and at no point shows any tendency to form sludge to any significant extent. If two fuels behave in this way when mixed, they can be considered compatible with each other. A heavy oil is incompatible if it shows a tendency to form deposits when diluted and / or mixed with other fuels. Typical incompatibility problems are sludge formation and resulting blockages of bunker and service tanks, lines, filters and centrifuge drums. In extreme cases, if there are incompatibility problems, the only remedy is to manually remove the accumulated sludge, which can be both time consuming and very costly.

Cat Fines

Patent 3121596 and 3121595

In general, ships' diesel engines burn fuel oil. Some oils are more contaminated by water and abrasive solids than others. To ensure reliable and effective operation, it is necessary to purify all fuel oils before injecting them into the engine.

The most common method of cleaning fuel on board is centrifugal separation. According to ISO 8217, the maximum allowable concentration of "Catalyst Fines" is 60 ppm. The engine manufacturers assume that the cleaning procedure will reduce the concentration to 10 - 15 ppm.

"Catalytic Fines" are residues from the catalysts used in the fuel cracking process. These particles are extremely hard and are capable of scratching or even cutting the metal components in engines. Any particles that are not filtered out by the centrifuge can lead to wear and damage to the motor.

XRF Analyser

CMTs HDXRF Analysers can measure the concentration of different elements within the oil. We offer one analyser for sulfur only and a second for multiple elements like P, Cl, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu and Zn.

The analysers are powered by High Definition X-Ray Fluorescence (HDXRF®) technology: an elemental analysis technique offering significantly enhanced detection performance over traditional XRF technology. This technique applies state-of-theart monochromating and focusing optics, enabling dramatically higher signal-to-background ratio compared to traditional polychromatic X-Ray fluorescence.


Insoluble are a build up in combustion engines due to the burning fuel in the engine. They are combustion related debris and oxidation products within the lubrication oil.

Regular monitoring of insoluble helps to prevent lacquer formation on hot surfaces, sticking of piston rings, wear of cylinder liner and bearing surfaces. The detergent property of the oil will also decrease, speeding further deterioration.

  • Detect insoluble from diesel engine combustion such as partially oxidized fuel, carbon, fuel ash, oil oxidation products and used lubricant additives.

  • Simple and quick to use even for untrained people.

  • The insoluble tests give you actionable results, helping to maintain your engine.

Acid Number

Acid Number or AN is an important oil parameter for hydraulic systems and gas engines. It is a measure of the organic and inorganic acids present within the oil.

Flash Point Tester

The CMT Flash Point Tester is an automated closed cup instrument using just a 2 ml sample size.

Increased flash point in engine oils to about 200°C is an early indication for fuel dilution which can result in crankcase explosion.

The flammability of a material also determines its safety classification and the regulations under which it must be handled, stored and transported.

Fuel Bacteria Test

Bacteria, moulds and yeasts can all grow rapidly in fuel tanks! Free water, warmth and condensation in the fuel form the basis for growth of the Diesel Bugs.

  • Provides evaluation of Diesel Bug count (bacteria, yeast and moulds altogether)

  • Easy to use

  • Allows fast and safe handling

  • Suitable for all qualities of diesel fuel inclusive biodiesel

Oil Test Cabinets

CMT offers four types of oil test cabinets. The cabinets are intended for wall mounting. These test cabinets, whose robust workmanship allows them to be used in harsh environments, are easy to handle and ideal for operation even by untrained personnel.

  • Fast and precise results for different oil parameters

  • Enable quick decisions on site

  • Allow action to be taken before fatal errors occur

On-site inspection capability allows the engineer or facility manager to perform an oil analysis quickly and easily. Detecting out-of-spec fuels or lubricants can identify potential problems before machine damage occurs.

Cold Filter Plugging Point / Pour Point

The wax-like solidification of fuel when exposed to low temperatures determines its temperature usability boundary. The relevant indicator for that is the CFPP (Cold Filter Plugging Point).
