Unfillable Polycarbonate pH Composite Electrode PRO6136
PRO6136 unfillable polycarbonate pH composite electrode is a practical laboratory pH electrode for routine measurement workflows where low maintenance, stable reference performance and direct BNC connection are required. The electrode combines a polycarbonate body, Ag/AgCl reference system, single POM junction, 0–14 pH range, 5–60 °C working temperature and standard BNC(Q9) connector in a compact Ø12 × 120 mm format. Its unfillable construction reduces routine handling because the electrode does not require electrolyte refilling during normal use.

COLO.SCIENCE — PH ELECTRODES / ELECTROCHEMISTRY / WATER QUALITY
Low-maintenance pH composite electrode for routine laboratory measurement
The PRO6136 unfillable polycarbonate pH composite electrode is intended for laboratories that need a robust, easy-to-use pH electrode for everyday aqueous sample measurement. Its sealed, unfillable design helps reduce maintenance compared with refillable electrodes, while the Ag/AgCl reference system and single POM junction support stable routine pH readings when the electrode is correctly calibrated, stored and maintained.
PRO6136 uses a standard BNC(Q9) connector for direct connection to compatible laboratory pH meters. Before ordering, the meter input should be checked to confirm BNC compatibility. If the instrument uses S7 or another input format, cable or electrode compatibility must be verified before quotation.

Applications and laboratory value
Water quality laboratories
PRO6136 is suitable for routine pH measurement in water quality workflows where a low-maintenance electrode and standard BNC connection are preferred.
Routine laboratory pH testing
The unfillable polycarbonate pH composite electrode design helps reduce handling complexity in daily pH testing with compatible benchtop or portable pH meters.
Education and training
PRO6136 is useful for teaching pH electrode structure, Ag/AgCl reference systems, calibration practice and correct storage routines.
Replacement electrode selection
The electrode is relevant when the existing pH meter requires a BNC(Q9) pH electrode and the laboratory wants a sealed, unfillable composite electrode.
How to choose the correct unfillable polycarbonate pH composite electrode configuration
When selecting the PRO6136 unfillable polycarbonate pH composite electrode, the complete measurement setup should be checked, not only the pH range. Confirm the meter model, BNC(Q9) pH input, sample type, expected pH range, working temperature, required accuracy and routine calibration procedure before ordering.
COLO.Science can help match PRO6136 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.
PRO6136 unfillable polycarbonate pH composite electrode for daily laboratory pH measurement
The PRO6136 unfillable polycarbonate pH composite electrode is a practical electrode for laboratories that need routine pH measurement with reduced maintenance. The sealed design removes the need for electrolyte refilling, while the polycarbonate body provides a robust format for everyday handling in general laboratory environments.
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. PRO6136 provides a compact pH composite electrode platform, while the final laboratory setup should be defined as a complete pH measurement system.
