Overview
SHANGHAI JINGTIAN SNB-3 digital display Rotational Viscometer is a wide range instrument with a viscosity measurement range of 160 to 80,000,000 mPa · s (up to 1mPa · s with 0 #rotor). The device is equipped with an LCD screen that can display in real time various parameters such as viscosity, shear rate, shear stress, speed, temperature, percentimeter torque, rotor number and the maximum viscosity value that can be measured at the current rotational speed of the selected rotor.
Features
1. The LCD screen displays comprehensive information, including viscosity, shear rate, shear stress, speed, temperature, percentile torque, rotor number and maximum measurable viscosity value.
2. Wide viscosity measurement range, up to 160~ 80,000,000mPa · s.
3. Equipped with a small number of sample adapters, suitable for rotors 21, 27, 28, and 29, with a small sample requirement (10~ 20mL), suitable for testing valuable samples.
4. Thermostatic bath with external circulation function can be connected to control the temperature of the tested sample.
5. Structural design for easy disassembly and cleaning.
6. Adopt continuously variable speed to adjust Rotor speed (0.1~ 99.9rpm).
7. Measurement accuracy is +/- 1% F.S., reproducibility is +/- 0.5% F.S.
Principle
The Viscometer is a Rotational Viscometer and works based on the Tack resistance experienced by the rotor when swirl/spin in the sample. The motor drives the rotor to swirl/spin in the sample at a set speed, and Sensor measurements the torque required to maintain the swirl/spin, which is proportional to the viscosity of the sample. By measuring torque and combining rotor geometry and speed, the instrument calculates and directly displays the viscosity value of the sample.
