Precision Simulator for pH and ORP Meters
  • Simulates pH and ORP electrodes
  • Manual temperature compensation from 0 to 50°C (32 to 122°F)
  • High impedance selection button


HI 8427 is 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 and 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 109 ohm. The unique tester is a "one of a kind" in the industry that eliminates the need for very expensive megaohm meters.

HI 8427 is supplied complete with HI 7858/1 BNC/BNC connection cable (1 m, 3.3' long), battery and instructions.
