Hei-TORQUE Value 400 - 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
