This viscosity meter is driven by a Japanese synchronous motor imported to rotate the rotor speed at a constant speed.
When the rotor rotates in liquid, the liquid may affect the viscosity of the rotors torque and the viscosity of the viscosity of the torque.
Conversely, the smaller the viscosity of the liquid, the less viscous torque that works on the rotors of the viscosity torque. Detected sensors are obtained after computer processing of the liquid viscosity measured
The device uses microcomputer technology to easily set the range (number of rotor and speed), the sensor detects digital data processing, clearly shows the number of Rotor Speed measurement settings and viscosity values measured on the display.
The NDJ-9S has four rotors (no 1, 2, 3, 4) and four rotational speeds (6, 12, 30, 60 rev/min).
It consists of 32 different combinations, allowing you to measure viscosity of various liquids within the measuring range.
