PRELIMINARY EXAMINATION

Remove the instrument from the packing material and examine it carefully to make sure that no damage has occurred during shipment. If noticeable damage is found, notify your Dealer or the nearest Hanna Customer Service Center.

Note: Save all packing material until you are sure that the

instrument functions correctly. Any defective item must be returned in the original packing together with the supplied accessories.

GENERAL DESCRIPTION

HI 8014, HI 8915 and HI 931000 are hand-held pH/mV meters with interchangeable plastic-body electrodes, simple controls on the front panel, low battery detector, large easy-to-read display, simple calibration procedure and lightweight ABS plastic housing.

• HI 8014 is an affordable portable pH/mV meter. The pH or mV ranges are easily selected with a rotary knob, as well as the °C range for manual temperature compensation. HI 8014 comes supplied with: HI 1230B combination, double-junction, gel pH electrode, one 9V battery and calibration screwdriver.

• HI 8915 is a portable pH/mV/°C meter that combines accurate pH measurements with a recorder output capability and automatic temperature compensation. Two recorder output terminals make it possible to attach a plotter or recorder directly to the meter for a hard copy of the measurements. Pressing the HOLD key will freeze the reading on the display. Calibration is performed using the two trimmers on the front panel. HI 8915 comes supplied with: HI 1230B combination, double-junction, gel pH electrode, HI 7669AW temperature probe, one 9V bat- tery and calibration screwdriver.

• HI 931000 is a compact, microprocessor-based pH/°C meter, which comes supplied with: HI 1217D combination gel pH/°C electrode with built-in temperature sensor and signal amplifier, one 9V battery and HI 710004 soft carrying case.
