Clarkson HI302N-1
Auto-Reverse Magnetic Stirrer with Speedsafe 115V
Hanna Instruments HI302N-1
HI312N is a powerful stirrer that stirs up to 5.0 liters (1.3 gallons). The HI302N model can stir up to 2.5 liters (0.66 gallons). It is often desirable to stir your samples in two directions. This will achieve maximum homogeneity and solubility. 
An advanced circuit allows HI302N and HI312N to reverse the direction of the stirring 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 will never be exceeded. During repeated testing, samples are often removed from the stirrer before the speed is reduced. This could cause the motor to accelerate until it destroys itself. HANNA stirrers incorporate a VCO device that stops the motor from accelerating as soon as the load is removed (Speedsafe).
In addition to this feature, HI312N also has an automatic feedback feature. The motor is electronically controlled to maintain the chosen speed as the load changes. If the viscosity or level (fluid weight) increases or decreases, the circuitry will adjust the output power to keep the speed constant.
