Product Description
Application:
VST-06 viscometer is specially designed for the quality control of industrial products in the manufacturing process, such as petrochemicals, paints, adhesives, as well as food, viscosity measurement covers a wide range. For example: gear oil of construction machinery. VST-06 viscometer is used to measure the resistance (torque) of the rotor caused by submerging the rotor by liquid.
Features
1. Compact structure, light weight, easy to carry, can be used by one hand
2. It can be recharged by alkaline battery, NiMH battery, AC adapter VA-05J
3. Unit display: MPa. S or DPA. S
4. VA-04 bracket can be selected for professional station measurement(optional)

Conversion of common viscosity units
1 centipoise (1cp) = 1 millipascal second (1MPa. S)
100CP = 1P
1000 MPa. S = 1 MPa. S
Conversion of dynamic viscosity and kinematic viscosity:
ETA = v.
Where η - dynamic viscosity of sample (MPa. S)
ν -- kinematic viscosity of sample (mm2 / s)
ρ -- density of the sample at the same temperature as the measured kinematic viscosity (g / cm3)
For liquids, the higher the pressure, the lower the temperature, the higher the viscosity, and the lower the pressure,
The higher the temperature, the lower the viscosity is.
The higher the temperature is, the higher the viscosity is, the lower the temperature is, the lower viscosity is
