Integrated pH, reference and temperature electrode for compatible laboratory meters
The PRO4153 3 in 1 pH composite electrode is intended for laboratories that want one compact pH electrode assembly instead of separate pH, reference and temperature probes. The integrated design supports routine pH measurement, temperature-enabled compensation and simpler installation with compatible pH meters.
This electrode is especially useful when a laboratory pH meter accepts a BNC(Q9) pH electrode connection and a 4-pin aviation temperature connection. Compatibility should always be confirmed before ordering, because pH and temperature input formats vary between instruments.
Key features
- 3 in 1 pH composite electrode combining pH indicator, reference and temperature probe functions.
- Ag/AgCl reference system for routine pH electrode workflows.
- pH range 0–14 for general laboratory measurement.
- 3 M KCl fill solution for the reference system.
- Polycarbonate sensor material for practical laboratory handling.
- Single fabric junction and Ø12 × 120 mm body format.

Applications and laboratory value
Water quality laboratories
PRO4153 is suitable for routine pH measurement in water quality workflows where a compact 3 in 1 electrode and temperature-enabled measurement support are required.
Routine laboratory pH testing
The integrated electrode configuration helps reduce setup complexity and supports practical pH measurement with compatible benchtop or portable pH meters.
Education and training
PRO4153 is useful for teaching pH electrode structure, reference systems, calibration practice and the role of temperature compensation in electrochemical measurement.
Replacement electrode selection
The electrode is relevant when the existing meter requires a BNC(Q9) pH signal connector and a 4-pin aviation temperature connection.
How to choose the correct 3 in 1 pH composite electrode configuration
When selecting the PRO4153 3 in 1 pH composite electrode, the complete measurement setup should be checked, not only the pH range. Confirm the meter model, BNC(Q9) pH input, 4-pin aviation temperature input, sample type, required temperature compensation and routine calibration procedure before ordering.
COLO.Science can help match PRO4153 with compatible pH meters, calibration buffers, electrode storage solutions and accessories so that the final configuration supports the intended laboratory method and daily measurement workflow.
PRO4153 3 in 1 pH composite electrode for daily laboratory pH measurement
The PRO4153 3 in 1 pH composite electrode is a practical electrode for laboratories that need a single sensor assembly for pH measurement, reference function and temperature support. The integrated construction reduces the number of separate probes and helps simplify routine pH measurement workflows where instrument compatibility is confirmed.
In daily use, the quality of pH measurement depends on more than the electrode specification. Buffer freshness, calibration frequency, sample temperature, electrode storage, junction condition and the selected pH meter all influence measurement stability. PRO4153 provides a compact 3 in 1 electrode platform, while the final laboratory setup should be defined as a complete pH measurement system.
