Overview
The NIRUN DV-79B Digital Viscometer is a printer-equipped precision measuring instrument with stepper motor direct drive and LCD LCD with blue backlight for accurate viscosity measurement of many fluids.
Features
1. Stepper motor direct drive, no gear, accurate speed
2. LCD liquid crystal with blue backlight, displaying a large amount of information
3. Display the maximum viscosity value of the rotor that can be measured at the current speed
4. Timing measurement function
5. The viscosity value shows continuous change
6. There is an alarm sound beyond the measurement range
7. Standard RTD Temperature Probe
8. Computer full-scale linear correction
9. AC Power Adapter 100V-240V, good anti-interference
Principle
The instrument directly drives the rotor swirl/spin through a stepper motor, measuring fluid resistance and converting it into viscosity values, and in combination with the RTD Temperature Probe monitors temperature in real time to ensure measurement accuracy.
Applications
Starch, Glue, Latex, Adhesive solvent, polymer solution, petroleum, paints, solvents, cosmetics, milk products, fruit juice
Steps
1. Connect the Power Adapter and turn it on
2. Choose the right rotor and measurement vessel
3. Set the speed and timing functions
4. Place the sample in the container and start the measurement
5. Read the viscosity value displayed by the LCD
6. Use the printer to output data (if required)
Notice
• Power frequency within 110~ 220V range
• Check whether the rotor is in good condition before use
• Avoid exceeding the measurement range to prevent alarm triggering
Periodically calibrate instruments to ensure accuracy
• Clean rotors and containers to prevent contamination of samples
