Remove the instrument from the packing material and examine it carefully to make sure that no damage has occurred during shipping. If there is any noticeable damage, notify your Dealer immediately.

Note: Save all packing materials until you are sure that the instru-

ment functions correctly. Any damaged or defective item must be returned in its original packing materials together with the supplied accessories.

GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

GENERAL DESCRIPTIONGENERAL DESCRIPTION

These waterproof Hanna instruments are heavy-duty pH meters designed to provide laboratory results and accuracy under harsh industrial conditions.

HI 9023C, pH/mV/°C meter utilizes an advanced customized microprocessor. The meter has three memorized buffer values (4.01, 7.01 and 10.01) and automatic buffer recognition to avoid errors during calibration. There are no trimmers, making calibration an easy process, even for non-technical personnel. Temperature effects are automatically compensated for, or can be manually adjusted. With HI 9023CHI 9023C

HI 9023C you can also measure ORP (Oxidation Reduction Poten-

HI 9023CHI 9023C tial) or Ion Specific. Millivolt measurements automatically switch from

0.1 to 1 mV resolution when the reading reaches 400mV. HI 9023C is supplied with HI 1230B combination double-junction gel

pH electrode, HI 7669/2W temperature probe, pH 4.01 and 7.01 (20 mL each) buffer solutions, sample vessel, 1.5V AA size batteries (4 each) and a rugged carrying case.

HI 9023CN, pH/mV/°C meter utilizes an advanced customized microprocessor. The meter has three memorized buffer values (4.01,

7.01 and 10.01) and automatic buffer recognition to avoid errors during calibration. Temperature effects are automatically compensated for.

electrode, pH 4.01 and 7.01 (20 mL each) buffer solutions, sample vessel, 1.5V AA size batteries (4 each) and a rugged carrying case.

HI 9024C and HI 9025C are pH/°C meters with a built-in microprocessor. A large dual-level LCD displays the pH and temperature simultaneously. The display has graphic symbols to make the calibration procedure easy to follow. The meters have 5 memorized buffer

values (4.01, 6.86, 7.01, 9.18 and 10.01), buffer recognition to avoid errors during calibration and automatic temperature compensation. You can use HI 9025C with ORP (Oxidation Reduction Potential)

or Ion Specific Electrodes. Millivolt measurements automatically switch from 0.1 to 1 mV resolution when the reading reaches 400 mV. To insure trouble-free operation, the meter's circuitry comes with built-in protection against electromagnetic interference.

HI 9024C and HI 9025C are supplied with HI 1230B combination double-junction, gel pH electrode, HI 7669/2W temperature probe, pH 4.01 and 7.01 (20 mL each) buffer solutions, sample vessel, 1.5V AA size batteries (4 each) and a rugged carrying case.

HI 9110 pH meter has simple manual temperature compensation and calibration which make this meter easy to use in laboratory and field. The calibration trimmers are sealed behind a protective cover so that they cannot be accidentally moved or readjusted by unauthorized persons.

HI 9110 is supplied with FC 100B combination double-junction, refillable pH electrode, calibration screwdriver, 1.5V AA size batteries (4 each) and a soft carrying case.

HI 9210 pH meter has simple manual temperature compensation and calibration with only two buttons, making it simple to use for even non-technical personnel. The calibration trimmers are sealed behind a protective cover so that they cannot be accidentally moved or readjusted by unauthorized persons.

HI 9210 is supplied with HI 1230B combination double-junction, gel pH electrode, calibration screwdriver and 1.5V AA size batteries (4 each).

HI 9210N pH/°C meter measures both pH and temperature. It has only two buttons, making it simple to use for even non-technical personnel. The calibration trimmers are sealed behind a protective cover so that they cannot be accidentally moved or readjusted by unauthorized persons.

HI 9210N is supplied with HI 1217D 4-in-1, gel, amplified pH/ C electrode, calibration screwdriver and 1.5V AA size batteries (4 each).

INITIAL PREPARATION

Each meter is supplied complete with batteries. Remove the back cover, unwrap the batteries and install them while paying attention to polarity.

HI 9023C, HI 9024C, HI 9025C:

To prepare the instrument for use connect the pH electrode and the temperature probe to the BNC and temperature sockets on the top of the instrument. The temperature probe can be used independently to take temperature measurements, or it can be used in conjunction with the pH electrode to utilize the meter's ATC capability. If the probe is disconnected, temperature can also be set manually with the UP and DOWN keys. To switch the instrument on, press and hold the

ON/OFF key for a fraction of a second. The meter has a built-in protection against electromagnetic interference and the delayed response of the keys assures that the commands are not mistaken for stray signals.

HI 9110 and HI 9210:

Connect the pH electrode to the BNC connector on the top of the instrument and press the ON/OFF key.
