The Wincom Rotary Viscometer is a precision laboratory instrument designed to measure the dynamic viscosity and rheological properties of liquid solutions, fluids, and semi-solids. Operating on the principle of rotational viscometry, it measures the torque required to rotate a spindle at a constant speed while immersed in the sample fluid. It is an essential tool for quality control and research in paint, coating, food, beverage, cosmetics, petroleum, and chemical manufacturing industries.

Technical Specifications

• Measurement Range: 1 to 100,000 mPa.s or up to 2,000,000 mPa.s (depending on the specific sub-model)

• Spindle Specifications: Standard rotor set included (No. 1, 2, 3, and 4 spindles)

• Rotation Speed Options: Variable configurations (e.g., 6, 12, 30, 60 RPM or fully digital adjustable speeds)

• Measurement Accuracy: +/- 1.0 percent of full scale range

• Measurement Repeatability: +/- 0.5 percent

• Power Supply: AC 220V, 50Hz

• Temperature Sensor: Optional RTD temperature probe for real-time sample temperature monitoring

Key Features

• Digital LCD Display: Provides direct readouts of viscosity values (mPa.s), spindle number, selected rotation speed, and percentage torque, eliminating manual calculations.

• Stepping Motor Drive: Equipped with a high-torque, low-noise stepping motor that ensures precise rotational speeds without any mechanical gear variations.

• Overload Protection: Built-in security mechanisms automatically protect the internal spring and sensor alignment if the sample viscosity exceeds the spindle capacity.

• Anti-Static Construction: The robust outer casing is built with durable anti-static materials to protect sensitive electronics from laboratory interference.

• Sturdy Lifting Stand: Includes a smooth manual lifting mechanism and leveling feet to ensure the spindle aligns perfectly inside the sample container every time.

Primary Applications

• Paints, Inks, and Coatings: Measuring the thickness and leveling properties of industrial paints, printing inks, varnishes, and resins to ensure smooth application.

• Food and Beverage Industry: Checking consistency in dairy products, chocolate syrups, sauces, honey, jams, and starch solutions during production.

• Cosmetics and Pharmaceuticals: Monitoring the viscosity of creams, lotions, shampoos, ointments, and gelatin formulas for product uniformity.

• Petroleum and Chemicals: Testing lubricants, engine oils, polymer solutions, adhesives, and liquid plastics for quality certification.
