HANNA HI 311N-1

The Hanna Instruments HI 311N is a heavy-duty stirrer that offers dual range precision that can stir up to 5.0 liters ( 1.3 gallons) . In addition to speed control, a limiter installed into the Hanna Instruments HI311N will assure that the maximum speed will never be exceeded . HANNA stirrers incorporate a VCO device that will stop the motor from accelerating as soon as the load is removed.

The Hanna Instruments HI 311N also has an automatic feedback feature. The motor is electronically controlled to maintain the chosen speed as the load changes. If the viscosity or the level ( fluid weight) increases or decreases, the circuitry of the Hanna Instruments HI 311N will adjust the output power.
