pH Composite Electrode (Blade spear) Ag/AgCl (BNC(Q9)) 0–14 pH for pH Meter
Blade spear Composite pH Electrode
OVERVIEW
This pH composite electrode (Blade spear) combines the pH indicator electrode and reference electrode into one practical body. Unlike a basic pH indicator electrode which requires a separate reference electrode, this composite design simplifies installation and reduces cable clutter for routine pH measurement workflows.
With a pH range of 0–14, Ag/AgCl reference system, unfillable design and POM (polyformaldehyde) sensor material, this electrode is a practical option for laboratories that need a robust and easy-to-use pH sensor. The BNC(Q9) connector must be matched with a compatible pH meter.
pH composite electrode for routine laboratory work combining pH sensing and reference system in one compact assembly. Features 0–14 pH range, Ag/AgCl reference, unfillable design, POM body and BNC(Q9) connection for compatible meters.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 match the instrument input used in your laboratory workflow. 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.
