General Electrode Notes
- pH electrodes are available as pH indicator electrode, composite electrode, and 3 in 1 pH composite electrode (with temperature probe).
- A pH indicator electrode needs to cooperate with a separate reference electrode.
- A composite electrode combines the pH indicator electrode and reference electrode.
- A 3 in 1 pH composite electrode combines the pH indicator electrode, reference electrode, and temperature probe.
- Temperature probes can adjust pH measurements by correcting the electrode slope according to the measured temperature.
- The connector must be compatible with the meter you are using. Options include S7 [S7-BNC(Q9) cable] and BNC(Q9).
Connector Options & Compatibility
Different meters may require different connection formats. Always confirm connector type before ordering.
