Oil Viscosity Measuring Instrument

Viscosity and temperature are considered to be inversely proportional.

Oil viscosity measuring instrument. The viscosity index test astm d 2270 is based on the kinematic viscosity of the oil at 40 c. Oils with a high vi. Viscosity index numbers above 95 are considered high. Control box can be up to 15 m 49 ft from the measuring head.

Absolute techniques typically use rotational viscometers whereas kinematic techniques will commonly use flow viscometers dependent on gravity. Viscosity can also be measured using absolute dynamic viscosity techniques and reported in centipoise. Use the rod to stir the oil and then measure the force required to stir each oil at the same rate. Second if your onsite instrument does not heat the oil to 40 c and most do not you are likely determining the oil s viscosity at the temperature of the onsite lab typically in the 20 c 25 c range and extrapolating again using a software algorithm to determine the viscosity at 40 c.

The force required to stir the gear oil will be greater than the force required to stir the turbine oil. In oil analysis viscosity is commonly measured using kinematic viscometers and reported in centistokes cst. Consistent use of the visgage can warn users of viscosity changes. The rm 100 l touch viscometer is ideal for measuring the viscosity of chemical and petroleum products cosmetics and pharmaceuticals food products building materials paint ink and coatings.
