The M 21 hotplate/stirrer in a cost effective design with built in advanced safety and user features. These hotplate stirrers all have superb performance such as soft-start for the stirring motor, PID control of the liquid and hotplate temperatures for fastest heat up time without overshoot and temperature stability, acid resistant epoxy-finished chassis and grade 304 stainless steel covers, combined with
a stainless steel shroud between hotplate and cover to avoid the entrance of spills into the interior. Features a direct display of the set and safety temperatures on the front panel of the instrument. Available with RS485-interface which enables easy setting and readout of all relevant parameters. Both the heating power and stirring speed are adjustable with easy to use knobs.
