Overview
NDJ-8S digital display Viscometer is an upgraded product of rotational viscometer of JINGQI brand. The instrument adopts advanced mechanical design, manufacturing process and microcomputer control technology, and has the characteristics of accurate data collection, high measurement Sensitivity, reliable test results and convenient operation. It is mainly used for the measurement of absolute viscosity of Newtonian liquids and apparent viscosity of non-Newtonian liquids. It is widely used in the measurement of viscosity of various fluids such as grease, paints, plastics, Coatings, Adhesives, detergents, etc.
Features
1, using professional mechanical design technology, manufacturing process and microcomputer control technology, accurate data collection, high measurement Sensitivity, reliable test results, easy to use and operate, beautiful appearance.
2. The display uses a white-backlit, high-luminance LCD display screen, which can directly display the rotor number, speed, viscosity, percentile torque, real-time temperature of the tested sample and the maximum range of the selected rotor at the current speed.
3. The instrument is equipped with RS232 communication interface as standard, which can communicate with the computer and print measurement results through the optional printer. The power supply adopts DC 12V and 24V adapters, which have strong anti-interference ability.
4. It can preset 4, 8 and 18 speed speeds, and can also adjust speed stepless to meet different range of measurement requirements. In addition to standard rotors (1 #, 2 #, 3 #, 4 #), ultra-low viscosity adapters (0 #rotors) and small sample adapters (21 #, 27 #, 28 #, 29 #rotors) can also be selected according to requirements.
5. It has the upper and lower limit alarm or digital flashing prompt function beyond the range, which not only protects the instrument but also saves measurement time.
6. The instrument is equipped with a standard temperature sensor, which can monitor the sample temperature in real time (Measurement range 0-200 ° C, accuracy +/- 0.1 ° C) to ensure measurement accuracy.
7. The instrument comes standard with a demonstration operation CD to guide users in real time.
Principle
The NDJ-8S digital display Viscometer works based on the principle of swirl/spin viscosity measurement. The instrument drives the selected rotor to swirl/spin at a uniform speed in the sample, and the Tack resistance to the rotor will form torque. The microcomputer control system accurately measures this torque, and combines the rotor specifications, speed and other parameters to calculate the sample viscosity value through the built-in algorithm, which is displayed on the LCD screen in real time.
Applications
Oil, paints, plastics, Coatings, Adhesives, detergents and other fluid viscosity measurement
Standards
The data did not mention specific compliance criteria
Steps
The information does not provide detailed operation steps, but it is mentioned that the instrument comes standard with a demonstration operation CD to guide the operation in real time.
