AUTO-REVERSE STIRRERS
HI 302N normal stirrer and HI 312N autospeed
stirrer allow to stir the fluid in both directions
and are ideal for powder mixing applications
to ensure a homogeneous final product and
complete dissolution of hard-to-wet powders.
The reverse stirring period is adjustable from
30 seconds to 3 minutes. When set to
1 minute, the fluid will rotate in one direction
for minute and then reverse its rotation for
another minute at the desired speed in a
repeated cycle until the stirrer is switched off.
1. Power indicator (LED lights up when the
stirrer is powered)
2. ON/OFF/SPEED knob, to turn the stirrer
ON and OFF, and set the stirring speed
(continuously variable up to the maximum)
3. REVERSE PERIOD knob with the ON/
OFF and continuously variable selection
of inversion cycle time in minutes, from
0.5 to 3 minutes
