Rotary type Visc osimeter NDJ-5S

Main technical specifications:

NDJ-5s/8s model digital viscosimeter is the upgraded product.

This instrument has the advanced machine design and MCU controller to

give the correct result.display shows the blue backlight, high-light LCD display make you see the result easily.

working principle

This instrument makes the rotor rotate in the same speed by torque sensor. The speed of the electromotor is decided by the program in SCM When the torsion which is directly proportional to sample’s sticky resistance is equal to the force from torque sensor in different direction, the viscosity will be showed on the LED after microprocessor’s working.

This instrument has the MCU to control the capacity(rotor and speed) and to calculate the data from the sensor before show the value on the display clearly, at the same time show the rotor,speed and percentage and so on.

NDJ-5S has 1,2,3,4 nubmer rotor and 6,12,30,60 r/m speed,so has 16 combinations, so can test every value in the capacity.

NDJ-8S has the 1,2,3,4 number rotor and 0.3,0.6,1.5,3,6,12,30,60 r/m speed ,so has 32 combinations to test the value in the capacity.
