Viscosity is very important criteria in process .To measure the viscosity at high temp. & pressure in reaction vessel is a critical phenomenon. This instrument operates on resonance frequency principle which is least sensitive to Vibration, shocks etc. Since there is no moving part, no wear & tear,No frequent maintenance & calibration. Process viscometer is designed to measure viscosity directly in Industrial Process by mounting on reactor or pipes in any position. It is compatible with process conditions like temp. Press, corrosion, clogging, humidity etc. It can go up to 350 * C temperature & 500 bar pressure.
