Viscosity Test

It is fundamental to maintaining the integrity of a lube oil film in preventing metallic contact, scuffing, micro-welding and wear of sliding surfaces. Therefore, CMT has developed a unique Viscosity Test, which is self usable and gives you the result within 10 minutes.

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, the viscosity can be calculated when measured.

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

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 and increases in viscosity due to oil contamination. It can not be used to get an actual viscosity, but you will get an idea of whether the viscosity is greater or smaller than the compared oil viscosity. It is essential that both oil measured do have the same temperature.
