User manual HANNA INSTRUMENTS HI 304N

[. . . ] Unlike conventional stirrers, all Hanna stirrers use the concept of pulse-driven drive to give the full power required to effectively stir the fluid regardless of the speed. This eliminates the need to start the motor at high speed and the user is now able to control the speed precisely. 3 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. Damages due to accidents, misuse, tampering or lack of prescribed maintenance are not covered. This warranty is limited to repair or replacement free of charge.

Operation of these instruments in residential area could cause unacceptable interferences to radio and TV equipments, requiring the operator to take all necessary steps to correct interferences. Any variation introduced by the user to the supplied equipment may degrade the instruments' EMC performance. Unplug the stirrers from the power supply before replacing the fuse. To avoid damages or burns, do not place these stirrers in microwave ovens. 6 7 HI 300N & HI 310N GENERAL PURPOSE STIRRERS 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 HI 300N Maximum Stirring Capacity HI 310N 2. 5 Liters 5 Liters (0. 66 gallons) (1. 3 gallons) Speed Range Min Max Auto-Speed 100 rpm 800 to 1000 rpm not applicable standard MAGNETIC STIRRER HI 300N POWER ON OFF MAX SPEED Power Supply HI 300N-1 HI 300N-2 HI 310N-1 HI 310N-2 Installation Category Cover Material 110/115 Vac, 50/60 Hz 220/240 Vac, 50/60 Hz 110/115 Vac, 50/60 Hz 220/240 Vac, 50/60 Hz II 1 2 HI 310 AUTOSPEED MAGNETIC STIRRER AISI 316 stainless steel POWER ON OFF MAX Environment SPEED 0 to 50ºC (32 to 122ºF); RH max 95% 180 x 180 x 70 mm (7. 1 x 7. 1 x 2. 8") 1. 4 kg (3. 1 lb. ) Dimensions 1.

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 2 3 HI 302N Maximum Stirring Capacity Speed Range Min.
