Viscosity is the most important indicator of an oil

It is fundamental to maintaining the integrity of a lube oil film, in preventing metallic contact, scuffing, microwelding and wear of sliding surfaces.

The Electronic Heated Viscosity Meter from CMT excels at measuring both fuel oil viscosity & lube oil viscosity. Applications include diesel engines, gas and aviation turbines, gear boxes, hydraulics and fuel oils. Verifying the correct grade of fuel delivered, calculating combustion performance, adjusting of fuel handling and injection systems, CMTs Electronic Viscosity Meter is there to make the users life easier. The Viscosity value, as a lube oils most important indicator, is providing an optimum film strength in system clearances, with minimum friction losses and leakage. With readings being uniquely provided directly in centistokes, it can measure at 3 temperatures. It also allows calculation of CCAI, storage or injection temperature and blending ratio.

The Viscosity Meter has been proven to be as accurate as laboratory methods

  • Measures viscosity at different temperatures and reports as Viscosity at 40, 50 or 100°C
  • Allows calculation of CCIA, storage or injection temperature and blending ratio
  • Suitable for all mineral oils down to 1.5 cSt up to 999 cSt

The CMT Viscotube uses a falling ball technique to measure the viscosity of oil in centistokes. The tube is inverted and the time the ball needs to fall down will be manually measured. With the time, ball size and temperature of the oil when measured the viscosity can be calculated. 

The CMT Viscotube comes supplied in a case with multiple balls for increased accuracy, a digital thermometer and a stop watch.

The CMT Viscosity Oil Test Kit gives a simple go / no-go result for viscosity. Typically it will detect 5-10% distillate fuel dilution of an SAE 30 to 40 engine oil as well as increases in viscosity due to oil contamination. It can not be used to get an actual viscosity but you will get an idea whether the viscosity is greater or smaller than the compared oil viscosity. It is essential that both oil measured do have the same temperature.
