Overview
NDJ-1 Dial Viscometer is a rotational viscometer produced by Shangtian Jingyi brand. It is a precision instrument for measuring the absolute viscosity of Newtonian liquids and the apparent relative viscosity of non-Newtonian liquids. The instrument has the characteristics of high measurement Sensitivity, reliable test results, easy operation, beautiful appearance, etc. It can be widely used in oils, paints, plastics, food, coatings, glues, Adhesives, Resin, chemical raw materials and other products.
Features
1. Adopt advanced mechanical design technology and manufacturing process, accurate data collection
2. The rotor is made of stainless steel 304, which is easy to clean and durable
3. Use a universal connector at the interface where the rotor is connected
4. Absolute viscosity measurement of Newtonian liquid, that is, dynamic viscosity
5. The lifting system adopts helical tooth strip/helical gear mode
6. Transmission gears are highly wear-resistant and high-performance engineering plastics
7. With data storage function, it can automatically store multiple sets of test data
8. Power supply: AC220V +/- 10%, 50Hz +/- 10%
Principle
The instrument is a Dial Viscometer, which is driven by a motor to make a constant speed swirl/spin. When the rotor swirl/spin in the liquid, the liquid will produce a viscosity torque acting on the rotor. The greater the viscosity of the liquid, the greater the Tack torque; conversely, the smaller the viscosity of the liquid, the smaller the Tack torque. The Tack torque acting on the rotor is detected by the Sensor, and the viscosity of the measured liquid is obtained after processing.
Applications
Grease, paints, plastic, food, paint, glue, Adhesive, Resin, chemical raw materials
Steps
1. Set range (rotor number and speed)
2. Immerse the rotor in the tested liquid
3. Start the instrument to make the rotor constant speed swirl/spin
4. Read the viscosity value displayed by the pointer
Notice
• Power frequency AC220V +/- 10%, 50Hz +/- 10% before use
• The rotor should be cleaned in time after use to keep the surface of stainless steel 304 clean
• Ensure that the rotor is fully immersed in the measured liquid during measurement
• The instrument should be used within the ambient temperature range of RT + 5 ° C to 35 ° C
• Avoid use beyond the viscosity range of 1~ 1X10⁵(mPa · s)
