Hanna pH and ORP Simulator

This is a wonderful instrument for troubleshooting and calibration.

HI 931001: Hanna Digital pH and ORP Simulator

Hanna Instruments pH and ORP Simulator  HI 931001


Digital pH and ORP Simulator
Precision Simulator for pH and ORP Meters
  • Perfect for testing pH and ORP controllers and pH meters
  • pH and mV ranges are user selectable using two small manual dials
  • Simulated value is displayed and transmitted as a mV signal to the attached instrument
  • Automatic temperature compensation at 25C (77F)
  • Very helpful in equipment diagnosis, calibration of chart recorders, etc.
  • Use this unit to reset ORP calibration points in a controller that is out of adjustment

It is sometimes difficult to work out whether a particular malfunction is due to the meter or the electrode. By simply connecting the HI 931001 to your meter's input socket and turning the dials, pH readings can be simulated from 0 to 14 pH in 0.01 steps. The output signals all correspond to pH values at 25C and your pH meter should display the same values that can be seen on the simulator's LCD. For the mV range, HI 931001 can simulate output from -1000 to 1000 mV in 1 mV steps.

HI 931001 is supplied complete with HI 7858/1 BNC/BNC connection cable (1 m, 3.3ft long), battery and instructions.
