Scope of application
Dv-79 rotary viscometer is a precision instrument for measuring the absolute viscosity of various Newtonian liquids and the apparent viscosity of non Newtonian liquids. If used with a specific rotor, the rheology of non-Newtonian liquid can also be measured. It has the characteristics of convenient use, stable performance and simple maintenance. It is suitable for measuring the viscosity of various fluids such as grease, paint, ink, coating, plastic, slurry, rubber, latex, detergent, resin, condensed milk, cream, medicine and cosmetics. It is used in textile, chemical industry, petroleum, electromechanical, medicine, food, light industry, construction, and other industries as well as colleges and universities, Necessary instruments for laboratories and analysis rooms of scientific research institutions and military industrial departments.
Product features
1. NDJ-79 upgraded product, all digital viscometer.
2. The invention patent of our company overcomes the disadvantage that domestic instruments can only sample in one revolution, and realizes the technology of single revolution and multiple sampling.
3. The high subdivision drives the stepper motor to rotate, the speed is accurate and stable, and the change of AC voltage frequency does not affect the accuracy of viscosity measurement.
4. For thixotropic non-Newtonian liquids, the timing function of the instrument can ensure good consistent data.
5. LCD with blue backlight function can directly display the viscosity, speed, percentile torque and the maximum viscosity of the rotor at the current speed. The viscosity value shows a continuous change. There is an alarm sound when the measurement range is exceeded.
6. It overcomes the disadvantages of inconvenient reading, low accuracy and poor stability of NDJ-79.
7. The operation is simple and convenient. There is no need to install the reducer manually for speed switching. Just press it gently on the instrument panel to easily shift the speed.
8. Before the instrument leaves the factory, the full range computer will automatically calibrate it.
