NDJ-8S Digital Rotational Viscometer

NDJ-8S Digital Viscometer ◆◆Applications This instrument is designed to measure the absolute viscosity (dynamic viscosity) of Newtonian liquids or, with optional data processing software, accurately measure and comprehensively analyze the apparent viscosity of non-Newtonian liquids. It is widely used in industries and research institutions such as oils and fats, ink, paint, coatings, dairy products, fruit juice, latex, glue, slurry, textiles, food, pharmaceuticals, adhesives, and cosmetics. Known for its accuracy, speed, intuitiveness, and ease of use, it is the preferred choice for clients across various sectors. ◆◆Main Features ◆Equipped with a 16-bit microprocessor for high-resolution stepper motor drive and LCD backlight display; ◆Program-controlled motor ensures measurement accuracy is unaffected by mains frequency fluctuations; ◆Measurement data is displayed directly on the LCD screen, eliminating the need for secondary calculations; ◆Real-time display of viscosity, rotational speed, percentage torque, rotor number, and sample temperature; ◆Features stable rotation speed, high accuracy, programmable design, and user-friendly operation; ◆Full-scale and multi-range linearity calibration via PC interface, with performance and functionality meeting advanced domestic standards; ◆Includes an RS232 communication interface (or optional USB interface) for connecting to a computer to print or store data; ◆Optional temperature probe for real-time temperature monitoring of samples; ◆Optional data processing software tracks changes in viscosity over time, rotational speed (or shear rate), and temperature, providing an effective method for analyzing the viscosity and rheological properties of non-Newtonian liquids. ◆◆Technical Specifications ◆Measurement range: 10 mPa·s to 2,000,000 mPa·s ◆Accuracy: ±2% (F.S.) ◆Rotor specifications: No. 1, 2, 3, 4 rotors ◆Rotational speeds: 0.3, 0.6, 1.5, 3, 6, 12, 30, 60 r/min ◆Measurement mode: Continuous measurement ◆◆Optional Accessories ◆Ultra-low viscosity adapter or No. 0 rotor, measurement range: 1–10 mPa·s; ◆Dedicated thermostatic water bath for viscometer; ◆RTD temperature probe; ◆Standard viscosity fluid; ◆External circulation constant-temperature cup; ◆Data acquisition and graphing software.
