Overview
Shanghai JINGTIAN NDJ-4S digital display Rotational Viscometer is a precision measuring instrument with a range of 20 to 2,000,000 mPa · s. Its LCD screen can display various information such as viscosity, shear rate, shear stress, Rotation speed, temperature, percentile torque, rotor number and the maximum viscosity value of the selected rotor at the current Rotation speed.
Features
1. Digital display LCD screen, which can display various information such as viscosity, shear rate, shear stress, Rotation speed, temperature, percentile torque, rotor number and the maximum viscosity value that can be measured at the current Rotation speed of the selected rotor.
The measurement range is wide, covering 20 to 2,000,000 mPa · s.
3. Provide a variety of rotor specifications (L1 #, L2 #, L3 #, L4 #) and Rotation speed gears (0.3/0 6/1.5/3/6/12/30/60rpm) to adapt to different measurement needs.
4. The reproducibility is +/- 1% F.S., and the Measurement accuracy is +/- 5% F.S.
Principle
The Viscometer works based on the swirl/spin Measurement principle. The instrument drives the selected rotor to swirl/spin in the sample at a set constant Rotation speed. Tack resistance is applied to the rotor as it swirls/spins in the fluid, generating torque. The instrument measures this torque value and calculates it based on parameters such as rotor specification and Rotation speed to finally obtain the viscosity value of the sample.
