Overview
PT-D445-1005B semi-automatic kinematical viscosity apparatus conforms the ASTM D445 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity). It is used to test the of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, η, can be obtained by multiplying the kinematic viscosity, ν, by the density, ρ, of the liquid. Under certain constant temperature. The range of kinematic viscosities covered by this apparatus method is from 0.2 to 300 000 mm2/s at all temperatures.

Features
1. Four viscometers improve the experimental efficiency.
2. Adopts high precision digital display temperature control meter, corresponds ASTM standard.
3. The apparatus adopts glass bath with good transparency, bottom with circular light, convenient for observation.
4. Motor stirs constant bath temperature.
5. Equipped with LCD screen, generating results automatically, calculating average and printing it out.
6. With stainless steel heater, baffle, corrosion resistance, long life.
