Hanna Instruments HI 8427 pH/mV Calibrator

The HI 8427 is a portable pH/mV simulator designed specifically for calibrating pH and mV (ORP) meters. Two calibration ranges are provided from 0 to 14 pH with temperature compensation and from -1900 to 1900 mV. A high impedance button and leakage LED are also provided to verify if the connection cable and pH meter insulation are in perfect condition.

The instrument has a BNC output connector.
