The Hanna Instruments HI-304N is a heavy-duty magnetic stirrer with a stainless steel cover and built-in tachometer. An advanced circuit allows the HI-304N to reverse the direction of the stir at a user selected interval. The interval can be adjusted from 30 seconds up to 3 minutes. In addition to precision speed control, a limiter will also assure that the maximum speed of 800 to 1000 rpm will never be exceeded (Speedsafe™).

When stirring a solution, to work with a constant speed is an important factor in ensuring that the best repeatability in tests and processes is achieved. Without a tachometer, there is no way of knowing the RPMs.
