Super rotational viscometer is a precision instrument used for accurately measuring the viscosity and rheological properties of liquids, semi-solid and non Newtonian fluids. It drives the rotor to rotate in the sample through a high-precision motor, calculates viscosity based on the relationship between torque and speed, and can cover a wide range from 1mPa · s to millions of mPa · s. The performance of the super rotational viscometer comes from the collaborative design of multiple highly integrated functional modules.

1、 High precision servo motor and torque sensor
Adopting a brushless DC servo motor with a speed control accuracy of ± 0.1%, coupled with a high-sensitivity strain torque sensor, it can detect micro Newton meter level torque changes, ensuring accurate measurement of low viscosity samples (such as solvents) and high viscosity pastes (such as toothpaste). Some models support stress/strain control mode to achieve true rheological analysis.
2、 Intelligent temperature control system
Integrated PT100 temperature probe and semiconductor temperature control module (or external circulating bath), temperature control range -20 ℃ to+200 ℃, accuracy ± 0.1 ℃. The temperature directly affects the viscosity value (for example, for every 1 ℃ increase, the viscosity of the oil decreases by about 2%), and precise temperature control is the key to data comparability.
3、 Multi functional rotor system
Standard configuration includes multiple geometric rotors:
Standard disc rotor (LV series): suitable for low to medium viscosity Newtonian fluids;
Cone plate/parallel plate: used for precise control of micro samples (<2mL) and shear rate;
Propeller or T-shaped rotor: specifically designed for measuring non-uniform systems (such as particle slurries).
All rotors are made of stainless steel or titanium alloy, with a surface finish Ra ≤ 0.05 μ m, reducing boundary slip errors.
4、 Intelligent control system and software platform
The 7-inch touch screen is equipped with an embedded operating system and supports a multilingual interface; Complex testing programs such as constant speed, gradient shear, thixotropic ring, and yield stress can be set; Supporting PC software for data export, curve fitting (such as power law models), and automatic report generation, in compliance with standards such as ISO2555 and ASTMD2196.
5、 Automatic recognition and security protection
Automatically identify the model and load corresponding parameters after inserting the rotor;
Equipped with overload protection, over temperature alarm, and no-load detection functions to prevent sensor damage caused by misoperation;
The shell has an IP54 protection level, is dust-proof and splash proof, and is suitable for both laboratory and workshop environments.
