Feature

●NDJ-1 rotary viscometer is a new instrument used for determining the liquid viscose capacity and the absolute viscosity. Measuring range: 10-100,000 mPa road.
●According to different equipments, different rotors (1,2,3,4) will be attached, it can be select with the velocity according to the viscosity of the liquid.
●PRINCIPLE: Synchronous motor rotates with stable rate, connect scale disk, through hairspring and rotating shaft, drives rotors to rotate.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.
●NDJ-1 has been widely used to determine and measure the liquid viscosity in many application such as grease, painting, plastic, pharmacy and adhesives.
●It is a precison instrument to monitor and control the stable quality of products in the manufacturing. The whole set of instrument has good quakeproof packing to ensure the precision of instrument.

How To Operate And Reading
1. Operation

  • Connect power supply, turn on the equipment, screw the speed knob, select velocity, relax pointer joystick, reading data will be displayed (about 20~30 seconds) after the pointer becomes stable. Press the pointer joystick after pointer becoming stable, cut power supply, then get the reading data. If the pointer isn’t in reading window after motor stop, you can press pointer joystick unceasingly, turn on or off time after time, after practice, you will be familiar with it.

2. Reading

  • For example, the viscosity of liquid is about 3000 mPa·s the settings should be as following: rotor 2 # with of 6 rpm, rotor 3 # with of 30 rpm
  • If you cant estimate the viscosity of liquid, it should choose a high value for real measurement. In general, if it is a high viscosity liquid, small rotor should be used with low velocity, if it is a low viscosity liquid, lager rotor should be used with high velocity.
  • Absolute viscosity = Reading x Coefficient ( coefficient corresponding to rotor and rpm )
