Clarkson HI322N-2
Timer Controlled Magnetic Stirrer 230V
Hanna Instruments HI 322N-2
Description:
HI 322N and HI 324N incorporate a timer control that will turn the motor off after the selected amount of time
has been reached. The time is adjustable from 5 minutes to 2 hours. This feature allows the user to carry out
other tasks without worrying about under or over stirring.
These units are heavy-duty stirrers, and can stir up to 5.0 liters (1.3 gallons), making them ideal for laboratory
and production use. Each model incorporates electronic controls that allow the user to precisely regulate the
speed, and a limiter ensures that the maximum speed is never exceeded (Speedsafe). Often, a sample is
removed from the stirrer before the speed has been reduced. In some cases, this can cause the motor to
accelerate until it destroys itself. HANNA stirrers incorporate a VCO device that will stop the motor from
accelerating as soon as the load is removed.
In addition, HI 322N and HI 324N have an automatic feedback feature with HI 324N also boasting an LCD
tachometer. The motor is electronically controlled to maintain the chosen speed even if the load changes. If the
viscosity or the level (fluid weight) increases or decreases, the circuitry will adjust the output power. The RPM
display guarantees repeatability in QC test and research by constantly displaying the RPMs.
