GENERAL 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 9023C you can also measure ORP (Oxidation Reduction Potential) 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. HI 9023CN is supplied with HI 1217D 4-in-1 amplified, gel pH/ C 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 3 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). 4 FUNCTIONAL DESCRIPTION HI 9023C & HI 9023CN SPECIFICATIONS HI 9023C & HI 9023CN HI 9023C Range HI 9023CN 1) 2) 3) 4) 5) 6) 7) 8) 9) 10) Electrode connector (BNC for HI 9023C and DIN for HI 9023CN) Temperature probe socket (HI 9023C only) Liquid Crystal Display CAL key to enter or exit calibration mode CFM key to confirm calibration °C and C keys for manual temperature setting (HI 9023C only) ON/OFF key to turn the instrument on or off RANGE key to select pH, C or mV Low battery indicator (additional decimal point) Mode indicator 5 0.00 to 14.00 pH ±399.9 mV (ISE); ±1999 mV (ORP) 0.0 to 100.0 C 0.0 to 70.0 C Resolution 0.01 pH 0.1 mV (ISE); 1 mV (ORP) 0.1 C Accuracy ±0.01 pH (@20°C/68°F) ±0.2 mV (ISE); ±1 mV (ORP) ±0.4 C ±0.5 C Typical EMC ±0.02 pH Deviation ±0.2 mV; ±1 mV ±0.2 C ±0.5 C Calibration Automatic with 3 memorized standard buffers (4.01, 7.01, 10.01) Temperature Automatic or manual Automatic Compensation 0 to 100 C (32-212 F) 0 to 70 C (32-158 F) Electrode HI1230B plastic body, HI1217D plastic body, combination pH, BNC 4-in-1 gel pH/ C, DIN 1 m cable (included) 1 m cable (included) Temperature Probe HI 7669/2W (incl.) not necessary Input Impedance 1012 Ohm Battery Type & Life 4x1.5V, AA size (alkaline batteries) approx. 400 hours of continuous use auto-shut off after 10 minutes of non-use Environment 0 to 50 C (32 to 122 F); 100% RH Dimensions 196x80x60 mm (7.7x3.1x2.4") (meter) 340x230x80 mm (13.8x9x3.1") (kit) Weight 425 g (15 oz.)

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 or 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. °C °C ON/OFF 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. HI 9210N and HI 9023CN: ON/OFF Connect the pH/ C electrode to the DIN connector on the top of the instrument and press the ON/OFF key. ON/OFF 11 12 pH MEASUREMENTS To take a pH measurement remove the electrode protective cap and simply submerge the tip (4cm/1½") of the electrode and the temperature probe (wherever applicable) into the sample to be tested. HI 9023C, HI 9023CN and HI 9210N To use the meter's Automatic Temperature Compensation feature, simply submerge the pH/ C electrode into the sample and wait for a couple of minutes. The pH electrode also houses the temperature sensor which will measure and adjust for the temperature effect automatically. HI 9110, HI 9210: To use the meter's Manual Temperature Compensation feature: Press the pH/ C key of HI 9110 or the RANGE key of HI 9210 to select the manual temperature mode. pH °C SET Turn the instru ...
