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

HI 9023C, pH/mV/°C meter

utilizes an advanced customized micro-

processor. 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 pro-
cess, even for non-technical personnel. Temperature effects are
automatically compensated for, or can be manually adjusted. With
HI 9023C

HI 9023C

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

HI 9024C

and

HI 9025C

are

pH/°C meters

with a built-in micropro-

cessor. A large dual-level LCD displays the pH and temperature
simultaneously. The display has graphic symbols to make the calibra-
tion procedure easy to follow. The meters have 5 memorized buffer
