Unfillable Polycarbonate pH composite electrode Ag/AgCl Φ12×120 mm BNC(Q9)
OVERVIEW
This unfillable polycarbonate pH composite electrode offers a maintenance‑free solution for routine pH measurements. The unfillable design eliminates the need for electrolyte refilling, making it ideal for high‑throughput laboratories, educational settings, and applications where minimal maintenance is desired. The polycarbonate body provides excellent impact resistance and durability, while the Ag/AgCl reference system ensures stable and reproducible measurements.
With a full pH range of 0–14, working temperature up to 60 °C, and standard dimensions of Φ12×120 mm, this electrode fits most laboratory glassware and electrode holders. The single POM (polyformaldehyde) junction provides consistent electrolyte flow and is resistant to clogging. The BNC(Q9) connector offers direct compatibility with the majority of laboratory pH meters.
Maintenance‑free, unfillable pH electrode with polycarbonate body, Ag/AgCl reference, single POM junction, and BNC(Q9) connector. pH 0–14, 5–60 °C, Φ12×120 mm — ideal for routine laboratory measurements with minimal upkeep.COLO.Science · Practical and robust equipment for everyday laboratory workflows.

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.
