Digital Viscometer
1. General
NDJ-5S Digital viscometer is a new digital product based on the single chip micro-processor technologies and
used for determining the liquid viscose capacity and the absolute viscosity. Comparing with other similar
products, this instrument has the following features:
High measuring accuracy;
Stable in measured display;
Easy operation and read-out;
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.
2 Main technical data
1) Measurement range: 1 ~2 x106 mPa•s;
2) Rotor types: 1#, 2#, 3# and 4# rotors;
3) Rotor velocity: 0.3, 0.6, 1.5, 3, 6, 12, 30, and 60 rpm;
4) Operation modes: manually or automatically select the rotor types and velocity.
5) Measurement error: ±2% (Newton liquid)
6) Dimensions: 370 mm X 325 mm X 280 mm (the base not included);
7) Net weight:6.8 Kg;
8) Operation conditions
a) Ambient temperature: 5°C~ 35°C；
b) Relative Humidity(RH): not greater than 80%;
c) Power supply: Voltage--220 V±10%, Frequency—50 Hz±10%;
d) No electro-magnetic interference, no severe vibration and no corrosion gases in
instrument surrounding area;
3 Working principle
1) The program-controlled motor rotates at the given velocity controlled by a program
and makes the rotary axis of the viscometer to revolve, and through a torque sensor,
then drives the standard rotors to rotate, the rotors will subject to a torque moment
proportional to liquid viscosity because of the liquid viscose hysterics. The torque
moment will be measured by the sensors and processed into the viscosity and
shown on the display. In order to extend the measuring range, 4 rotors with 8
different velocities were used in this instrument.
