Application Note: Troubleshooting A pH Electrode

Source: Thermo Scientific

Many factors affect performance of a pH electrode. When performance degrades, it is always a challenge for the analyst to identify the cause(s). Common troubleshooting procedures, which include evaluation of slope, electrode drift, time response, and accuracy, take considerable time. The Thermo Scientific Orion Star LogR Meter provides a new, quick and easy tool for electrode diagnostics based on the measuring the sensing bulb resistance.
