HI 8427

pH and mV Precision Simulator
HI 8427 is designed specifically to simulate pH and ORP electrodes to confirm proper functioning of your meter. Standard pH electrode ranges are selectable with a dial on the front panel.

Provided with a universal BNC connector, this unit is also a high impedance tester, for cable and connector inspection with a leakage sensitivity of 109 ohm. This unique tester is a “one of a kind” in the industry that eliminates the need for very expensive MΩ meters.
