Specification :

The HI 9125N heavy-duty waterproof pH/ mV 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 9125N 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.
