Stepless Speed Viscometer - High-Range Digital Viscometer - 12-80,000,000 mPa·s - 0.1-200 rpm

The Master Science Stepless Speed Viscometer is a high-range rotational viscometer with continuously variable speed, allowing the operator to set exactly the shear rate a method requires. Depending on the model, it measures from 12 mPa·s up to 80,000,000 mPa·s.

An RTD temperature probe reads sample temperature in real time, and optional software adds automatic data collection, storage and comparison of historical results.

Key Benefits

• Any speed you need: stepless control sets the exact rpm specified in a standard or customer method.
• Huge measuring span: the Master Science Stepless Speed Viscometer reaches 80,000,000 mPa·s on the S3 model.
• Temperature on screen: the RTD probe shows sample temperature next to the viscosity value.
• High precision: ±1 % accuracy and ±0.5 % repeatability of full scale.
• Expandable: software, baths, heaters and adapters extend the application range.

Common Laboratory Problems and How This Viscometer Helps

How the Master Science Stepless Speed Viscometer handles difficult viscosity tests:

• Method needs a non-standard speed: stepless control sets any speed in range.
• Extremely thick materials: high-range models measure up to 80 million mPa·s.
• Unknown sample temperature: the RTD probe reads it directly.
• Comparing batches over time: optional software stores and compares data.
• Low viscosity liquids: an ultra-low adapter extends the lower range.
