Measurement

Place the electrode in the solution to be tested while stirring it gently. The measurement should be taken after the stability tag ( ) has disappeared.

The ORP (mV) value is displayed on the first LCD line and the temperature on the second LCD line.

Note: If measurements are taken successively, rinse the probe thoroughly in distilled or deionized water to eliminate cross-contamination. After cleaning, rinse the probe with some of the sample to be measured.

Maintenance
