A separate on/off switch for heating prevents an unintentional heat-up. If heating is switched on the on/off button in illuminated for visual control. An independent safety circuit switches off heating at an operator-programmed temperature value above your set temperature. An additional operational safety step is required to change parameters which prevents unwanted changes to the actual setting. The digital display allows for easy setting and monitoring of values on the illuminated readout. Speed setting from 30rpm to 1400rpm at an accuracy of 1% and temperature setting up to 300°C. Hotplate residual heat indicator in the digital display illuminates when unit is turned off and hotplate temperature is above 50°C to prevent accidental operator injury.
