Description

Viscometer VT-04 (High viscosity) employs the rotating cylinder principle. A rotor turning at constant speed is inserted into the liquid to be measured. The resistance to rotor movement caused by the viscosity (torque) is measured using a special mechanism to obtain direct readings in millipascal-seconds (mPa.s) or decipascal-seconds (dPa.s).

Applications :
– Compact size, can be operated with one hand.
– Battery powered design allows use anywhere.
– Quick startup shows reading immediately after turn-on.
– Direct reading in millipascal-seconds or decipascal-seconds (SI units)
– Stand and AC adapter available as options.
