pH Composite Electrode High Temperature Resistance –5 to 110 °C
OVERVIEW
This pH composite electrode with high temperature resistance is specifically designed for applications requiring reliable pH measurement across a wide temperature range from –5 to 110 °C. The robust glass body and ceramic junction ensure stable performance even under thermal stress, while the Longlife reference system provides extended electrode lifetime and minimal drift. Ideal for industrial processes, hot water monitoring, and demanding laboratory conditions where standard electrodes may fail.
With a full pH range of 0–14 and standard dimensions of Φ12×120 mm, this electrode fits most laboratory glassware and industrial vessels. The S7 connector (requires an S7‑BNC(Q9) cable for meters with BNC input) ensures compatibility with a wide range of pH meters. Perfect for chemical, pharmaceutical, environmental, and quality control applications that involve elevated temperatures.

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.
