Viscometer VT-04 (High viscosity)

Viscometer VT-04 (High viscosity) is designed for a wide range of viscosity measurements. It is suitable for checking industrial substances such as heavy oil, paint, and adhesives. It can be used for quality control in manufacturing processes of foodstuffs and other products. When inspecting construction vihicles and other machinery, the unit can serve to measure not only the viscosity of hydraulic oil but also of light spindle oil, gear oil, etc.

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.
