Hanna HI 8427

HI 8427 High Impedance Tester for pH and ORP Electrode Cable

Electrode Emulation at pH 0, pH 2, pH 4, pH 7, pH 10, pH 12, pH 14 confirms pH meter performance.
Manual temperature compensation allows temperature simulation.
High impedance testing of cable and connectors.

HI 8427 Designed specifically to simulate pH & ORP electrodes and to confirm proper functioning of your meter. Standard pH electrode ranges are selectable with a dial on the front panel. The pH range is pH 0, pH 2, pH 4, pH 7, pH 10, pH 12, pH 14 with the mV range being -1900 mV, -350 mV, +350 mV and +1900 mV. Manual temperature compensation from 0 to 50°C (32 to 122°F) allows temperature simulation. Provided with a universal BNC connector, this unit is also a high impedance tester, for cable and connector inspection with a leakage sensitivity of 10¹² ohms. The unique tester is a "one of a kind" in the industry that eliminates the need for very expensive megaohm meters. The HI 8427 comes supplied complete with a BNC/BNC cable.
