Long glass pH electrode for deep vessels, tall containers and routine laboratory use
The PRO6147 pH composite electrode long is intended for applications where a standard-length electrode is not practical. Its 260 mm length supports measurements in deep vessels, larger flasks, tall sample containers and other setups where extended reach improves positioning and measurement handling.
The electrode uses a glass body, ceramic junction, Longlife reference and 3 M KCl fill solution. The S7 connector allows connection through compatible S7 input or an S7-BNC(Q9) cable when used with pH meters that have BNC input. Connector and cable compatibility should always be confirmed before ordering.
Key features
- Long pH composite electrode with extended Φ12 × 260 mm body.
- pH range 0–14 for broad routine laboratory measurement.
- Glass body for chemical resistance and stable laboratory handling.
- Ceramic junction for practical reference electrolyte contact.

Applications and laboratory value
Deep vessel pH measurement
PRO6147 is useful when the sample container is taller than standard laboratory beakers, or when the electrode must reach a lower measurement point inside the vessel.
Routine water quality laboratories
The broad 0–14 pH range and glass body design make the electrode suitable for routine aqueous pH testing when the application requires extended reach.
Industrial and process samples
The long body format can support sample checks in taller process containers, laboratory vessels or QA/QC setups where reach and stable positioning are important.
Replacement electrode selection
PRO6147 is relevant when a compatible pH meter requires an S7 electrode or an S7-BNC(Q9) cable connection for BNC input meters.
How to choose the correct long pH composite electrode configuration
When selecting the PRO6147 pH composite electrode long, the complete measurement setup should be checked, not only the pH range. Confirm the meter model, electrode input, S7 cable requirement, sample container depth, required immersion length, sample type, temperature range and routine calibration procedure before ordering.
COLO.Science can help match PRO6147 with compatible pH meters, S7-BNC(Q9) cables, calibration buffers, electrode storage solutions and accessories so that the final configuration supports the intended laboratory method and daily measurement workflow.
PRO6147 pH composite electrode long for extended-reach laboratory pH measurement
The PRO6147 pH composite electrode long is a practical solution for laboratories that need an extended-reach pH electrode with a slim glass body. The Φ12 × 260 mm format allows easier access to deep sample containers while maintaining a standard laboratory electrode diameter. This makes PRO6147 suitable for applications where standard pH electrodes are too short or difficult to position correctly.
In daily use, the quality of pH measurement depends on more than the electrode specification. Buffer freshness, calibration frequency, electrode storage, junction condition, sample temperature, cable quality and the selected pH meter all influence measurement stability. PRO6147 provides a long glass electrode platform with ceramic junction, Longlife reference and S7 connector, while the final laboratory setup should be defined as a complete pH measurement system.
