HI 300N is heavy-duty stirrers. The HI 300N can stir up to 5.0 liters (1.3 gallons). This makes them perfect for laboratory use as well as use in production. Electronic controls are incorporated into these stirrers that allow the user to regulate the speed with greater precision. In addition to speed control, a limiter will assure that the maximum speed will never be exceeded (Speedsafe). Often, in the lab, a sample is removed from the stirrer before reducing the speed. This would normally cause the motor to accelerate until it is destroyed. HANNA instruments stirrers incorporate a VCO device that will stop the motor from accelerating as soon as the load is removed. In addition to these, HI 310N 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. The HI 310N magnetic stirrer, stainless steel cover, is supplied with magnetic stir bar. Speed range: minimum 100rpm, maximum 800 to 1000rpm.
