The instrument is a 16-bit microprocessor core control circuit, no gear driven, RTD temperature probe real-time monitoring and measurement of viscosity temperature, blue screen liquid crystal digital display directly display viscosity, speed, percentage torque, rotor number and the selected rotor at the current speed of the maximum viscosity value can be measured. Eye-catching according to the key, stable speed, accurate measurement. Equipped with RTD temperature probe and RS232C standard output interface, data can be saved, compared and recorded after connecting to a PC (optional fully automated data acquisition function via a PC interface).
