📋 Product Overview
Application profile
Routine pH measurement: suitable for laboratory pH workflows where pH, reference and temperature functions are required in one electrode assembly.
3 in 1 configuration: combines pH indicator electrode, reference electrode and temperature probe in one composite electrode body.
Compatible pH meters: intended for meters that accept BNC(Q9) pH input and a 4-pin aviation temperature input.
Water quality and electrochemistry: suitable for general laboratory pH measurement, calibration practice and routine sample checking.
Why 3 in 1 pH electrode?
Reduced cable complexity: pH signal, reference function and temperature support are combined in one practical electrode setup.
Temperature-enabled measurement: the temperature probe helps compatible meters apply temperature compensation or slope correction.
Ag/AgCl reference system: common reference system for routine pH electrode applications.
Practical materials: polycarbonate sensor material and single fabric junction support everyday laboratory handling.
