Key Features

• Direct Digital Interface: The smart LCD display provides direct readings of current viscosity (mPa.s), percentage torque, spindle number, selected speed, and real-time sample temperature.

• Micro-Step Motor Drive: Built with a modern micro-step electronic motor that eliminates old mechanical gears, providing silent operation and highly stable rotational velocities.

• Auto-Search Function: Includes an intelligent automated search feature that helps users select the best combination of spindle number and speed for an unknown sample.

• High Temperature Resistance Probe: Supports an optional high-precision RTD temperature sensor to measure sample heat during tests, ensuring data uniformity.

• Over-Range Protection: Features automatic audio-visual warnings and rotational cutoffs if the test fluid exceeds the safety torque limits of the internal sensors.

Primary Applications

• Food and Chemical Processing: Measuring the precise thickness and quality profiles of starch pastes, chocolate, milk products, syrups, adhesives, and glues.

• Paints, Inks, and Coatings: Monitoring the viscosity of latex paints, printing inks, specialized chemical coatings, and resins to control thickness.

• Cosmetics and Medicines: Evaluating the stability and texture consistency of skin creams, medical ointments, gels, shampoos, and liquid soaps.

• Petroleum and Automotive Oils: Grading lubricants, synthetic motor oils, crude extracts, and liquid polymers under temperature conditions.
