Dear Customer, Thank you for choosing a Hanna product. Please read this instruction manual carefully before using the meter. If you need additional technical information, do not hesitate to e-mail us at tech@hannainst.com. These meters are in compliance with directives. WARRANTY All Hanna Instruments products are warranted for two years against defects in workmanship and materials when used for their intended purpose and maintained according to the instructions.
Each stirrer is equipped with an opto-sensor for speed monitoring, and a speed limiter circuit that prevents hazardous operation when the load is suddenly removed. The power required to effectively stir a fluid is affected by the torque load on the stirrer which is dependent on the capacity, type and viscosity of the fluid. The speed of the stirrer decreases as the torque load increases and vice versa, unless the power delivered changes accordingly.
ELECTRICAL CONNECTIONS FUNCTIONAL DESCRIPTION AND SPECIFICATIONS See the following pages for specifications of each model. The capacity is referred to stirring water with a viscosity of 0.001 N·s/m2 at 25ºC. Specifications for all models 2 1 3 1. ON/OFF switch for power supply 2. Fuse holder for 400 mA/250 V fuse 3. AC power cord. Unplug the stirrers from the power supply before replacing the fuse.
HI 300N & HI 310N GENERAL PURPOSE STIRRERS HI 300N These general purpose stirrers are suitable for daily stirring applications in the laboratory. HI 300N normal stirrer and HI 310N autospeed stirrer are covered with a corrosion resistant stainless steel top. 1 2 MAGNETIC STIRRER HI 300N POWER ON OFF MAX SPEED 1 HI 310 AUTOSPEED MAGNETIC STIRRER ON OFF Speed Range Min Max 2.5 Liters 5 Liters (0.66 gallons) (1.
HI 301N & HI 311N TWO-SPEED STIRRERS HI 301N HI 301N normal stirrer and HI 311N autospeed stirrer, are ideal for long duration stirring which require slow speed and accurate speed control (for example in electrolysis applications). The selectable HIGH/LOW range allows to set the speed precisely. 1 MAGNETIC STIRRER HI 301N HIGH ON OFF Speed Range Low High 2.5 Liters 5 Liters (0.66 gallons) (1.
HI 302N & HI 312N AUTO-REVERSE STIRRERS HI 302N 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.
HI 303N TWO-SPEED STIRRER WITH TACHOMETER HI 303N stirrer incorporates an LCD tachometer. This model allows precise stirring repeatability by using two separate ranges. In each range, the speed can be fine tuned for exacting accuracy.
HI 304N AUTO-REVERSE STIRRER WITH TACHOMETER HI 304N is a heavy-duty stirrer with a built-in tachometer. An advanced circuit allows to reverse the direction of the stir at an interval that can be adjusted from 30 seconds up to 3 minutes. HI 304N Maximum Stirring Capacity Speed Range Min. Max.

HI 322N & HI 324N TIMER-CONTROLLED STIRRERS HI 322N HI 322N and HI 324N are autospeed stirrers equipped with timer control to start and automatically stop the stirring process after an user-selectable period (from 5 minutes to 2 hours). They are the ideal stirrers for routine applications where the required stirring time is known, and for non-Newtonian fluids whose viscosities change during stirring or Newtonian fluids up to 5 liters capacity. 1 2 3 Speed Range Min. Max.
OPERATIONAL GUIDE FOR HI 300N and HI 310N • • Make sure that the SPEED knob (on the front panel) and the ON/OFF switch (on the rear panel) are in OFF position. Place a beaker or glass container at the center of the top of the stirrer, and place the stirring bar in the beaker. • Allow sufficient time for the mixing operation to attain uniform rotational flow. • When stirring is complete, turn the SPEED knob to the OFF position.
OPERATIONAL GUIDE FOR HI 301N, HI 303N and HI 311N • Select the low or high range with the HIGH/ LOW switch as required. MAGNETIC STIRRER HI 303N HIGH SPEED IN RPM • MAGNETIC STIRRER HI 303N SPEED IN RPM Make sure that the SPEED knob and the ON/OFF switch are in the OFF position. POWER POWER HIGH OFF Place a beaker or glass container at the center of the top of the stirrer and place the stirring bar in the beaker.
OPERATIONAL GUIDE FOR HI 302N, H I 304N and HI 312N • • • HI 314 AUTOSPEED MAGNETIC STIRRER Make sure that the SPEED knob and the ON/OFF switch are in the OFF position. rpm ON 0.5’ MAX OFF POWER Place a beaker or glass container at the center of the top of the stirrer and place the stirring bar in the beaker. Pour the liquids to be mixed into the beaker. Do not fill up to the brim and leave sufficient space to prevent spillage during stirring.
OPERATIONAL GUIDE FOR HI 322N and HI 324N • • Make sure that the SPEED knob and the ON/OFF switch are in the OFF position and the START/RESET switch is in RESET position.
