New NDJ-8S, Digital display Rotary viscometer,  high precision authentic Measure Absolute Viscosity of Newtonian Liquid

NDJ-8S is a Digital rotary viscometer which has been upgraded. This viscometer adopts advanced mechanical design technology, manufacturing process and micro computer control technology, make the data acquisition correct and the display adopts LCD with blue backlight and high brightness, make the displayed data clear.

NDJ-8S Digital rotary viscometer is used for determining the liquid viscose capacity and the absolute viscosity. Comparing with other similar products, this instrument has the following features:

l High measuring accuracy;

l Stable in measured display;

l Easy operation and read-out;

l Excellent in Anti- interference.

NDJ-8S has been widely used to determine and measure the liquid viscosity in many applications such as grease, painting, pharmacy and adhesives.

1. Main technical data

1) Measurement range: 10~2×10⁶mPa.s 

2) Rotor types: 1#, 2#, 3# and 4#  rotors; (You can determine viscosity as low as 0.1mPa.s with 0# rotor.)

3) Rotor velocity: 0.3,0.6,1.5,3,6,12,30,60 rpm; automatic

4) Measurement error: ±5% (Newton liquid)

5) Power supply: 220V±10%   50z±10%

6) Ambient temperature: 5°C~ 35°C;Relative humidity: ≤80%

2. Working principle 

This instrument is a rotary viscometer, rotor could be rotated constantly by the variable speed motor. Rotate the standard rotor, the rotors will subject to a torque moment proportional to liquid viscosity because of the liquid viscose hysteresis. The torque moment will be measured by the sensors and processed into the viscosity and shown on the display.

This instrument adopts micro computer technology, range (rotor number and speed) can be set and the data determined by sensor can be processed conveniently, and the rotor number,speed,viscosity etc. can be displayed clearly on LCD.

The instrument was designed and manufactured with 4 rotors (1#, 2#, 3#, 4#) and 8 different velocity (0.3,0.6,1.5,3,6,12,30,60 rpm), which enable it to measure any viscosity value in the given range.
