Powerful electronic stirrers that feature a smooth start operation which prevents spills and splashing media. The speed ramps up slowly until set speed has been reached. Both models feature safe start and stop of operation via an intuitive glass slide touch panel to avoid accidental start-up. An overtemperature sensor shuts off the unit in dangerous heat-up situations, ideal for unattended continuous operation. All units are designed for continuous 24-hour operation, including challenging high viscosity applications in polymer research. High torque levels give better mixing results in less time, maintenance-free motors reduce repairs and down time. Hei-TORQUE Value 400 and Hei-TORQUE Precision 400 units have two speed gears.

• Excellent mixing results in challenging high-viscosity media
• Newest motor generation for maximum power at minimum noise level below 50 db
• All stirrers maintain exact speed under changing loads
• Through-shaft design allows the impeller position to be adjusted, so height adjustments are more convenient
• A single grip allows user to re-adjust the height of the stirrer on optional telescope stand
• Hei-TORQUE Precision models have digital 3,2" display for ease of operation

Hei-TORQUE Value stirrers are ideal for standard stirring tasks. They are designed to mix and disperse media that require non-reproducible results in high-viscosity applications. They have a digital 2,4" display.

Hei-TORQUE Precision stirrers allow for pre-programmed profiles and save these profiles in memory, are suitable for interval operation and are ideal for demanding tasks which have to be reproducible and documentable. The additional features (display speed and torque graph life, timer/countdown/real time settings) and operation modes allow adjustment to individual application and USB interface saves all process data in a digital file.
