HI 931001

pH and mV Precision Simulator
Sometimes it is difficult to recognize whether a particular malfunction is due to the meter or the electrode. By simply connecting 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 25°C and your pH meter should be able to check the span of your pH meter.

For the mV range, HI 931001 can simulate output from -1000 to +1000 mV in 1 mV steps.
