Simulates pH and mV values:

• 0-14 in 2 pH increments, +/- 414 mV
• Tests pH meters, recorders and instruments with mV input
• BNC connector, operates by 9-volt battery
• Accuracy: 1%

When a pH meter has incorrect readings, most likely the problem lies within the electrode. In order to verify this problem, the pHault Finder can test and calibrate a pH meter by simulating the electrode signal from 0-14 pH in increments of 2 pH units.

A high-low impedance switch helps determine if the pH meter's high impedance has been compromised and also allows calibration of low impedance recorders and meters.
