Features & Applications:

This Hanna waterproof portable pH / mV / temperature meter has been designed with the latest microprocessor technology to provide laboratory results and accuracy under harsh industrial conditions. A large dual-level LCD displays the pH and temperature simultaneously. Graphic symbols are provided for helping the user during the calibration process. The pH calibration procedure is automatic with 5 memorized buffer values (4.01, 6.86, 7.01, 9.18 and 10.01), buffer recognition to avoid errors and automatic temperature compensation. The HI 9125 can be used with ORP (Oxidation Reduction Potential) electrodes. The resolution automatically switch from 0.1 to 1 mV when the reading exceeds 400 mV. The meter is also provided with the BEPS (Battery Error Prevention System) feature, which automatically turns the instrument off when the battery level is too low to ensure reliable readings.
