Shanghai Jingqi Digital Viscometer NDJ-8S, Shanghai Jingqi Instrument Co., Ltd. (CAT#: STEM-AI-1002-YJL)

Shanghai Jingqi Digital Viscometer NDJ-8S, model NDJ-8S is manufactured by Shanghai Jingqi Instrument Co., Ltd.
NDJ-8S rotational viscometer is an upgraded product of our company's rotational viscometer. The instrument adopts mechanical design technology, manufacturing process, and microcomputer control technology, and the data acquisition is accurate. The display uses a white backlight, high-brightness LCD display screen, and the data display is clear. This instrument has the characteristics of high measurement sensitivity, reliable test results, convenient use and operation, beautiful appearance and so on. It is an instrument used to measure the absolute viscosity of Newtonian liquids and the apparent viscosity of non-Newtonian liquids. It can be widely used in the measurement of various fluid viscosities such as oils, paints, plastics, medicines, coatings, adhesives, and detergents.

Measuring range: (10~2000000) mPa·s
Rotor specification: (1~4) rotor
Rotor speed: preset eight gears (0.3-60) r/min, stepless speed regulation
Measurement error: ±1% (F·S)
Power supply: AC 220V; 50Hz
Working environment: Ambient temperature (5~35) ℃, relative humidity ≤80%.

The instrument adopts advanced mechanical design technology, manufacturing technology and microcomputer control technology, with accurate data collection, high measurement sensitivity, reliable test results, convenient use and operation, and beautiful appearance.
The display adopts a white backlight, high-brightness LCD display, which can directly display the rotor number, speed, viscosity, and percent torque. The real-time temperature of the sample to be tested and the maximum range of the selected rotor at the current speed. The instrument is equipped with RS232 communication interface as standard, which can communicate with the computer and print the measurement results through the optional printer. The power supply adopts DC 12V and 24V. The adapter has strong anti-interference ability. Viscosity-temperature curve software can be selected to realize man-machine dialogue. Its function and performance have reached the same level as foreign countries, so it is cost-effective, and it is deeply loved by users as an instrument for schools, laboratories and scientific research units.
4 gears, 8 gears and 18 gears can be preset, and at the same time, the speed can be adjusted steplessly to meet the measurement requirements of different ranges. In addition to the normal standard rotors (1#, 2#, 3#, 4#), the instrument can also be equipped with ultra-low viscosity adapters (0# rotors) and small sample adapters (21#, 27#, 28#, 29# rotor).
The instrument has an upper and lower limit alarm or digital flashing prompt function for exceeding the range. It not only protects the instrument from damage, but also saves measurement time because of timely adjustment of the rotor or rotating speed.
The instrument is equipped with a standard temperature sensor to monitor the temperature of the sample in real time to ensure the accuracy of the measurement. The measurement temperature range is 0-200°C, and the measurement accuracy is ±0.1°C.
The instrument comes standard with a demonstration operation CD to guide users in real-time operation of the instrument.
