Viscosity Meter Viscometer Digital Rotational Viscometer for Oil Paint Coating

Introduction:

• The newly designed NDJ series rotary viscometer not only has modern aesthetic elements in appearance, but also has convenient operation, accurate measurement and complete functions, many of which are not available in domestic similar products at present.
• The instrument adopts high-performance imported microcomputer chip, imported stepping motor and other key components, and has the functions of LCD backlight display, program setting, automatic control, timing measurement, automatic scanning, level setting, error alarm and so on. 
• The screen directly displays information such as viscosity, temperature, timing measurement time, rotating speed, rotor number, specific torque in percent, and viscosity that can be measured in the selected range. 
• The linearity of each gear of the viscometer is automatically corrected by the computer according to the nominal value of the standard sample to ensure that the instrument has high sensitivity, high precision and high repeatability. The measured data is accurate, reliable and repeatable.

Application:

• NDJ series can measure the viscosity of Newtonian liquid or the apparent viscosity of non-Newtonian liquid. The rheological properties of non-Newtonian liquids can be analyzed by selecting data processing software. 
• Widely used in oil, paint, coating, slurry, textile, food, medicine, adhesive, cosmetics and other fluid and semi-fluid production industries, scientific research units and universities.
• Rotary viscometer is widely used in chemical industry, food industry, pharmaceutical industry, coating industry, cosmetics industry, etc. It is used to evaluate the fluidity and viscosity characteristics of liquids. 
• They are very important for quality control, product development and research and provide accurate and reliable viscosity measurement results.

Main features:

• The measured data can be displayed directly on the LCD screen without secondary calculation.
• Adopt microcomputer driving technology and imported stepping motor, with accurate speed, stability and reliability.
• Using switching power supply technology, the range of voltage and frequency is wide, and the fluctuation of power supply will not affect the measurement accuracy. 
• The horizontal display device is under the operation panel and can be adjusted when sitting, which is very convenient (new function). 
• The display value of viscosity value is accurate to two decimal places, that is, 0.01mPa.S (full range) (new function).
• It has the function of timing measurement, which is very practical for detecting non-Newtonian liquids (new function).
• A temperature probe can be selected to measure the temperature of the tested sample in real time.
• With automatic scanning function, the instrument can automatically recommend the appropriate combination of rotor and speed.
• The viscosity range that can be measured by the selected combination can be automatically displayed.
• With a printing interface, it can be directly connected to a micro printer to print various data (new function).
• Optional data processing software can record the change of viscosity with time, rotating speed or rotor (shear rate) and temperature in real time, which provides a good method to understand the viscosity and rheological characteristics of non-Newtonian liquids.
