Leírás és Paraméterek
High speed laboratory stirrer designed for intensive stirring tasks for quantities up to 20 l (H2O). It automatically adjusts the speed through microprocessor controlled technology within the speed range of 0/150 - 6000 rpm. Safety circuits installed ensures automatic cut-off in an anti-stall or overload conditions. Continuous comparison of shaft speed to desired speed is maintained and variations are adjusted automatically. This guarantees a constant speed even with changes in viscosities of the sample. The included precision shaft is 280 mm long and has a maximum immersion depth of 220 mm.
- Digital speed display
- Infinitely adjustable speed
- Cone seat for precision shaft
- Overload protection
- Short-term overload operation
- Slim casing
- Quiet operation
- Error code display
