Hei-TORQUE Precision 100

P/N: 501-61020-00

High-end model

The professional stirrer for demanding tasks: several options for individual settings as ramps and interval operation. USB and RS 232 interfaces allow for documentation and reproducibility, e.g. with the free Hei-Control software (for up to four devices)

These stirrers are ideal for demanding tasks which have to be reproducible and documentable. The huge number of additional features and operation modes allow for perfect adjustment to your individual application

Accurate torque indication shows any viscosity changes
Constant speed even under changing loads

Digital 3.2” display for ease of operation:
• Allows for preprogrammed profiles
• Saves these profiles in memory
• Interval operation
• Watch rpm and torque graph life
• Timer / Countdown / Real time settings

All performance-related parameters can be set individually:
• Intensity of the start operation - from slow to fast
• The rotational speed can be limited to avoid splashing media
• The torque limit prevents damage to the impeller, e.g. when using fragile impellers in high viscous media

Newest motor generation provides maximum power at minimum noise level
Safe start and stop of operation via slide touch panel to avoid unintended stirring

Including free Hei-Control software for dependable automation of all processes. Control up to four devices simultaneously. Also compatible with magnetic stirrers MR Hei-Connect and MR Hei-End of the Hei-PLATE series

Hei-TORQUE Precision 100 - Product Advantages


The electronic stirrers feature individual setting of the start operation, which prevents spills and splashing media. The speed ramps up slowly until your set rpm has been reached


An optional shaft guard prevents accidents


Non-sparking motors for additional safety


Important for continuous operation: the motor will be switched off if a high thermal load situation occurs to increase safety in your lab and to prevent accidents


Safe start and stop of operation via slide touch panel to avoid accidental start-up


To protect your stirrer against corrosion and short-circuits, all models comply with the protection class IP 54


Setting a rotation speed limitation prevents splashing media


Unique Quick-Chuck for immediate and convenient “one-hand” impeller changing - without tools


Opening the safety ring blocks accidental operation


An audible signal confirms a tight fit of the impeller
