Electrode Simulator (pHault)
- Simulates pH and mV values 0-14 in 2 pH increments, ± 414 mV
- Tests pH meters, recorders and instruments with mV input
- Accuracy: 1% of scale or ± mV, whichever is greater
- BNC connector, operates by 9V battery
When a pH meter has incorrect readings, most likely the problem lies with 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.
