The NDJ-8S+ Micro Printer Rotational Viscometer is a high-performance, versatile laboratory measuring instrument designed to meet the needs of viscosity measurement of different fluids. Thanks to its digital interface, the device offers a wide viscosity measurement range from 1 to 2,000,000 mPa·s, covering a wide range of samples from low to high viscosity. Rotors 1/2/3/4 as standard, and 0 rotors as an option further extend the measurement capabilities for low-viscosity samples. The rotational speed is set to 0.3/0.6/1.2/3/6/12/30/60 rpm to meet the needs of diverse experiments. The viscometer has high-precision measurement capabilities with a reproducibility of ±1%F.S, a measurement accuracy of ±2%F.S, and a display resolution of up to 0.01 mPa·s, ensuring the reliability and accuracy of measurement results. The system is functionally rich and supports routine measurement, curve measurement, recording, viscosity conversion and printing functions, and is equipped with USB and RS232 data interfaces for easy data transmission and recording, and can store up to 50 measurement records.
In addition, the device supports switching between Chinese and English operating languages to adapt to the usage habits of different users. The NDJ-8S Rotational Viscometer has a compact design, with a lifting stroke of 250mm, an overall dimension of 280×260×395mm, and a net weight of about 5kg, which is convenient for laboratory operation and storage. Its Operating Environment temperature range is 0°C40°C, and the Relative Humidity is 20% 80%, which is suitable for a variety of laboratory conditions. The device uses a 100240V, 5060Hz power adapter to ensure stable operation worldwide.
