Product Introduction
The Digital Rotational Viscometer – MRX-NDJ5S is a laboratory viscosity measurement instrument developed for quantitative evaluation of liquid flow resistance and absolute viscosity. It is designed for applications where reliable viscosity data is important for material formulation, quality control, and process development. The instrument covers a broad measurement range from 1 to 100,000 mPa·s (cP), allowing it to handle a wide variety of low- to high-viscosity materials.
Based on a microprocessor-controlled measurement system and gearless rotational drive structure, the MRX-NDJ5S provides stable spindle rotation and precise viscosity measurement. Its digital display presents the measured viscosity together with temperature, rotational speed, torque percentage, spindle number, and the maximum measurable viscosity associated with the selected spindle and speed. This gives operators direct access to the key parameters required during laboratory testing.
An RTD temperature probe continuously monitors the sample temperature during measurement, helping users evaluate viscosity under controlled thermal conditions. The instrument also incorporates an RS232C standard output interface for data communication with compatible external systems, making it suitable for laboratories that require digital measurement records or instrument integration.
The four standard spindle speeds of 6, 12, 30, and 60 rpm provide flexibility for different sample characteristics and test conditions. Four standard spindles are included, while an optional No. 0 spindle can be selected when required. With its combination of broad measurement capability, straightforward operation, stable display, and temperature monitoring, the MRX-NDJ5S is suitable for battery slurry research as well as testing of coatings, paints, adhesives, oils, food products, pharmaceutical fluids, cosmetics, and other viscous materials.
