NDJ-5S Digital Rotary Viscometer with Stand, Base and Transport Case

The NDJ-5S Digital Rotary Viscometer with Stand, Base and Transport Case is a laboratory instrument designed to measure the viscosity of liquids using a rotating rotor and torque-based measurement mechanism. It supports viscosity testing of Newtonian fluids and apparent viscosity measurement of non-Newtonian fluids across a specified range of 10–100,000 mPa·s. The instrument uses a synchronous motor to maintain rotor speed and an electronic display to present measurement values and operating parameters. The included stand, base, four-rotor set, and transport case support laboratory setup, measurement procedures, and equipment handling.

Technical Performance & Design

• Core Function: Measures liquid viscosity through rotational resistance applied to a submerged rotor, with the resulting torque converted into a displayed viscosity value.
• Measurement Range: 10–100,000 mPa·s for the NDJ-5S model.
• Measurement Accuracy: ±3% for Newtonian fluids, as specified in the supplied product information.
• Rotor Speeds: Selectable speeds of 6, 12, 30, and 60 rpm.
• Digital Display: LED digital display presents rotor model, rotational speed, real-time viscosity, temperature, and torque percentage, according to the supplied specifications.
• Measurement Principle: A synchronous motor drives the rotor at a controlled speed. Viscous resistance produces torque that is detected and processed to determine the viscosity reading.
• Rotor Configuration: Includes four standard rotors, numbered 1, 2, 3, and 4, for different measurement conditions.
• Measurement Selection: Rotor size and rotational speed can be selected according to the expected viscosity. Smaller rotors and lower speeds are recommended for higher-viscosity liquids, while larger rotors and higher speeds are recommended for lower-viscosity liquids.
• Fluid Compatibility: Suitable for measuring the absolute viscosity of Newtonian fluids and the apparent viscosity of non-Newtonian fluids.
• Application Areas: Applicable to viscosity testing of inks, coatings, adhesives, greases, fruit juices, dairy products, cosmetics, pharmaceutical formulations, biological fluids, rubber compounds, slurries, and pulp.
• Included Equipment: Supplied with a stand, base, standard four-rotor set, and transport case, as indicated by the product title and supplied specifications.
