Overview
JINGHAI DV-2 + PRO rotational viscometer is a digital (LCD) Viscometer, using a 16-bit microcomputer processor as the core of the stepping motor high subdivision drive technology. The instrument has the characteristics of smooth and accurate speed, programmed design, easy operation, alarm function, etc. The screen can directly display viscosity, speed, percentile torque, rotor number and the maximum viscosity value measurable at the current speed. Its circuit adopts patch technology, compact structure, Measurement performance reaches professional level.
Features
Adopt 16-bit microcomputer processor and stepper motor high-subdivision drive to ensure smooth and accurate speed.
2. Digital LCD screen with blue backlight, display comprehensive information, including viscosity, speed, percentile torque, rotor number and current measurable maximum viscosity value.
3. The buttons are clearly marked, programmed, and easy to operate.
4. Equipped with alarm function.
5. The main control board and driver board use patch technology, with professional circuit design and a reasonable and compact structure.
6. Measurement and correction of full scale and each gear Linearity through PC interface, Measurement performance reaches the same type of professional level abroad.
Principle
The rotational viscometer works based on the swirl/spin measurement principle. The instrument drives the selected rotor at a uniform speed swirl/spin in the sample, and the rotor generates torque when subjected to the resistance of the sample Tack. The instrument accurately measures and processes the torque signal through a microcomputer processor, combines the rotor specifications and speed parameters, and goes through an internal calculation program to finally display the sample viscosity value directly on the LCD screen.
Applications
Chemical, Petroleum, Food, Pharmaceutical, Coatings, inks, Adhesives, Cosmetics, Research and Education
Steps
1. Install and connect the Power Adapter.
2. Select the appropriate rotor according to the estimated viscosity value and install it on the instrument.
3. Immerse the rotor into the sample to be tested at the specified mark.
4. Turn on the power and set the required measurement speed through the button.
5. Start the measurement and read the viscosity value after the display value is stable.
6. After the measurement is completed, turn off the power and clean the rotor.
Notice
• Please use the standard Power Adapter of the instrument to ensure that the input voltage is 220V +/- 10% and the frequency is 50 +/- 1Hz.
• When selecting the rotor and speed, ensure that the measurement values are within the range of the instrument (1 to 2,000,000 mPa · s) and torque.
• Be careful when installing and removing the rotor to avoid damage to the connecting shaft.
• Ensure that the rotor and sample cup are clean before measurement, and the rotor immersion depth should be accurate.
The instrument should be placed in a stable and non-strong electromagnetic interference environment.
• Please keep it safe when not in use for a long time.
