Overview
PINGXUAN NDJ-1S rotational viscometer is an instrument widely used in oil, paints, Stock, Spinning & weaving, food, Adhesive, cosmetics and other production industries and R & D institutions. It uses a 16-bit microcomputer processor as the core of the stepping motor high subdivision drive, LCD backlight display, with the advantages of accurate, fast, intuitive and simple measurement. The screen directly displays viscosity, Rotation speed, percentile torque, rotor number and the temperature of the measured liquid. Measurement performance and function reach the same type of professional level in China.
Features
1. Large backlit LCD display, can display rotor number, Rotation speed, viscosity, torque percentage, sample temperature, shear rate and shear stress
2. With automatic scanning function, it can automatically recommend the best combination of rotor and Rotation speed to ensure High Accuracy of test
3. A variety of rotors can be used in one machine: ordinary rotors (1 #, 2 #, 3 #, 4 #) and high viscosity rotors (5 #, 6 #, 7 #)
4. Using professional accuracy calibrating technology, the accuracy and linearity of each file are all measured and corrected by external computer with standard silicone oil of different viscosity
5. With over-range alarm function
6. Optional temperature measurement Probe, real-time measurement of the temperature of the test sample, Temperature Measurement range 0~ 100 ℃, temperature measurement accuracy 0.1 ℃
7. With RS232 (or optional USB2.0) interface, connect to the computer
8. Standard data processing software, real-time recording of viscosity changes with different shear rates, time and temperature
Principle
The instrument uses a high-subdivision drive technology of stepper motor with a 16-bit microcomputer processor as the core. The viscosity is measured by the resistance of the rotor when swirling/spinning in the liquid. The screen directly displays information such as viscosity, Rotation speed, percentile torque, rotor number and the temperature of the measured liquid. Measurement and correction of full scale and each gear Linearity are carried out through the PC interface.
Applications
Oil, paints, Stock, Spinning & weaving, Food, Adhesive, Cosmetics and other production industries and R & D institutions
Steps
1. Select and install the appropriate rotor
2. Turn on the instrument, set the Rotation speed or use the automatic scanning function
3. Immerse the rotor in the tested liquid
4. Read the viscosity, Rotation speed, torque percentage, temperature and other information displayed on the screen
5. Can connect to the computer through RS232 or USB interface, use data processing software to record data
Notice
• Ensure that the rotor is properly installed and cleaned
• Avoid over-range use, the instrument has over-range alarm function
• When using the temperature sensor, pay attention to the temperature measurement accuracy of 0.1 ℃, the range is 0~ 100 ℃
• Periodically calibrated with standard silicone oil via external computer to ensure accuracy
When connecting to the computer, ensure that the interface is compatible (RS232 or optional USB 2.0).
