GENERAL DESCRIPTION
The HI 9124 and HI 9125 are state-of-the-art waterproof, heavy-
duty pH meters designed to provide laboratory results and accuracy
under harsh industrial conditions.
A large dual-level LCD, with clear indications related to the electrode
and instrument status, pH and temperature displayed simultaneously,
and user friendly graphic symbols during calibration.
The pH calibration procedure is automatic with 5 memorized buffers
(4.01, 6.86, 7.01, 9.18 and 10.01), buffer recognition and
automatic temperature compensation.
The HI 9125 can be used with ORP (Oxidation Reduction Potential)
electrodes. mV measurements automatically change from 0.1 to 1 mV
resolution when the reading reaches 700 mV.
