Premium glass pH electrode for pure water and Tris buffers featuring ceramic junction, Longlife reference, and S7 connector. pH 0–14, 0–80 °C, Φ12×120 mm — ideal for demanding laboratory applications.COLO.Science · Practical and robust equipment for everyday laboratory workflows.
Product Overview
The premium glass pH electrode for pure water and Tris is engineered to overcome the challenges of measuring pH in low‑conductivity media and Tris buffer solutions. The ceramic junction provides a stable liquid junction potential, while the Longlife reference system ensures long‑term reliability and reduces maintenance. The robust glass body offers excellent chemical resistance across the entire pH range. With standard dimensions of Φ12×120 mm, it fits easily into beakers, flasks, and other common laboratory vessels.
Compatibility notice — connector and meter matching are essential
This electrode features an S7 connector and requires an S7‑BNC(Q9) cable for use with meters having BNC input. Please confirm compatibility with your meter before ordering. For meters with direct S7 input, no cable is needed.

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.
| Connector / Option | Notes |
|---|---|
| S7 | This electrode features S7 connector. Use with S7‑BNC(Q9) cable for meters with BNC input. |
| BNC(Q9) | Common pH electrode connector format. Can be adapted via S7‑BNC(Q9) cable. |
