Overview
The NIRUN DV-79B digital Viscometer is a digital viscosity measurement instrument with stepper motor direct drive technology and a gearless design to ensure accurate Rotation speed. It is equipped with an LCD liquid crystal with a blue backlit display that displays a large amount of information, including the maximum viscosity value of the rotor measurable at the current Rotation speed, and has measurement timing function, continuous viscosity change display and out of Measurement range alarm.
Features
1. Stepper motor direct drive, gearless design, Rotation speed accurate
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 Rotation speed
4. Timing measurement function
5. The viscosity value shows continuous change
6. Measurement range beyond the alarm sound prompt
7. Standard RTD temperature sensor
8. Computer full-scale linear correction
9. AC Power Adapter 100V-240V, good anti-interference
Principle
The DV-79B digital Viscometer directly drives the rotor swirl/spin through a stepper motor, and the gearless drive ensures a stable and accurate Rotation speed. During the measurement process, the instrument calculates the viscosity value according to the resistance of the rotor in the fluid, and displays it in real time through the LCD display. Standard RTD temperature sensor monitors sample temperature, and computer full-scale linear correction ensures Measurement accuracy.
Applications
Starch, glue, emulsion, solvent Adhesive, polymer solution, petroleum, paints Coatings, solvents, cosmetics, milk products, products, fruit juices
Steps
1. Connect the Power Adapter and turn it on
2. Choose the right rotor and measurement vessel
3. Pour the sample into the measurement vessel
4. Set Rotor speed and timing parameters
5. Start the measurement and observe the LCD display
6. Read the viscosity value and adjust the parameters if there is an alarm prompt
7. Shut down and clean equipment after measurement
Notice
• Power supply voltage in 110~ 220V range, Frequency matching 50Hz/60Hz
• Check whether the rotor is in good condition before use to avoid damage
• Sample temperature should be controlled between 0 and 120 ° C during measurement
• Adjust the rotor or Rotation speed in time when the viscosity range is exceeded
• Regularly clean rotors and measurement containers to prevent contamination
Avoid use in strong interference environments to ensure measurement accuracy
