3 in 1 pH Composite Electrode Ag/AgCl (BNC(Q9) & 4-pin aviation) 0–14 pH for pH Meter
OVERVIEW
PRO4153 is a 3 in 1 pH composite electrode designed to combine the pH indicator electrode, reference electrode and temperature probe in one practical body. This integrated configuration simplifies installation, reduces cable clutter and supports routine pH measurement workflows with compatible laboratory meters.
With a pH range of 0–14, Ag/AgCl reference system, 3 M KCl fill solution and polycarbonate sensor material, PRO4153 is a practical electrode option for laboratories that need a compact and easy-to-use pH sensor with temperature-enabled measurement support. The BNC(Q9) & 4-pin aviation connector must be matched with a compatible instrument.
Integrated 3 in 1 pH electrode for routine laboratory work combining pH sensing, reference system and temperature probe in one compact assembly. PRO4153 supports practical pH measurement workflows with 0–14 pH range, Ag/AgCl reference, 3 M KCl fill solution and BNC(Q9) + 4-pin aviation connection for compatible meters.COLO.Science · Practical and robust equipment for everyday laboratory workflows.

Product Overview
PRO4153 3 in 1 pH composite electrode is intended for users who want a practical all-in-one electrode configuration. Unlike a basic pH indicator electrode, which requires a separate reference electrode, this model combines the sensing components into one assembly. In addition, the integrated temperature probe helps compatible meters adjust pH measurements by correcting the electrode slope according to the measured temperature.
Compatibility notice — connector and meter matching are essential
The connector must be compatible with the meter you are using. General connector options mentioned for this electrode family include S7 [S7-BNC(Q9) cable] and BNC(Q9). Model PRO4153 is specified with BNC(Q9) & 4-pin aviation connection. Please confirm compatibility with your meter before ordering.
