PRELIMINARY EXAMINATION

HI 190M, HI 190MB and HI 200M are compact and
lightweight magnetic stirrers. They incorporate an electronic
control that allows the user to regulate the speed with great
precision. In addition to speed control, a limiter will assure
that the maximum speed (1000 rpm) will never be exceeded.
HI 190M and HI 190MB have a plastic cover that will resist
the harmful effects of chemicals that are accidentally spilled.
HI 200M is provided with an AISI 316 stainless steel cover.
This model is ideal for applications that involve exothermic
reactions.

Each stirrer is supplied complete with a magnetic stir bar (L
