  • Page 2: Main Technical Data

    1：Operating Principle and Using NDJ Series Digital Viscometer (NDJ-5S-8S) is a smart instrument, depending on the technology of A 16-bit high-performance single chip,which has totally changed the previous rotor method. Stepper motor runs accurately and stably as the setting speed procedure. And then torque sensor will drive rotor rotation in a constant speed.

    （2） Installation 1. Take out the base, lifting column and handle from the packing box, and screw the column into the base respectively. (the rack surface is aligned with itself), and fasten the viscometer handle to the lift block. 2. Rotate the lifting button to adjust the tightness of the upper and lower lifting, and then put the T-shaped block behind the instrument into the handle and tighten it (make the left and right sides of the instrument flat).

    4. Press "START" , the instrument enters the running state. 5. Press "STOP" , the instrument stops working. Press "SCAN", the instrument will detect the viscosity of the liquid and automatically recommend the appropriate rotor and speed. NDJ-5S RANGE TABLE...
  • Page 6 NDJ-8S RANGE TABLE 7: Precaution 1. When the instrument works at room temp, the temp fluctuation of the tested sample should be within ±0.1℃, otherwise it will seriously affect the measurement accuracy. 2. Please look out the aperture angle percentage, its value should be kept 20%-85%.
  • Page 7 6. Rotor connector should be put on protective cap when the instrument is moved or transported. 7. Turbid liquid, emulsion, high polymer material and some high viscosity liquid, which all belong non-Newtonian liquid. Their apparent viscosity and velocity are not linear relationship. So, when you use different rotors, velocity, and measurement time, their viscosity measurement may be different, not the mistake of instrument testing.
