Viscosity/Density Meter

CMTs Viscosity/Density Meter combines two very important parameter for the condition monitoring


The density of the oil has direct implications on all other parameters of the oil.


To high or low viscosity decreases the function of the oil and makes all parts of the machinery vulnerable.


The Viscosity/Density Meter from CMT combines both tests in one device for quicker workflows.

Viscosity is fundamental to maintaining the integrity of a lube oil film. Lubrication is very important to prevent metallic contact, scuffing, micro welding and wear of sliding surfaces.

  • Measuring the oil viscosity provides an early detection of contamination, fuel ingress and shear thinning.
  • Suitable for all mineral oils or fuels down to 1.5 cSt up to 999 cSt (heated Viscometer only)
  • Allows to calculate the combustion performance (CCAI) of fuel or injection/storage temperature

The right amount of fuel cannot be determined by volume or weight alone. Depending on the injection temperature these values might vary widely. Density is required for quantity calculations and also to determine the optimum size of the gravity disc for the centrifuge. Diesel/fuel oil density also gives an indication of other fuel characteristics, including specific energy and ignition quality (CCAI). The density is used to confirm the quantity and grade of fuel delivered.

  • Ensure the correct amount and grade of fuel has been delivered to your ship
  • Ensure you have been supplied with fuel and not a mixture from fuel and gas (cappuccino effect)

The Viscosity/Density Meter can measure at 25°C, 40°C, 50°C or 60°C and displays results at 40°C, 50°C and 100°C vl. It also allows to measure very high viscosities with pin point accuracy.
The Viscosity/Density Meter is supplied with a hydrometer. Density is measured at 50°C and directly shown converted to 15°C, giving fast, accurate results. No calculation is needed.

As with all CMT Devices, the software is easy and intuitive to simplify the procedure as much as possible. All steps are easily explained on the screen.
