COLO.SCIENCE — PH ELECTRODES / HF ACID TITRATION / WATER QUALITY
HF-resistant pH composite electrode for acid titration workflows
The PRO6151 pH electrode HF acid titrate is designed for pH measurement during titration work in aggressive fluoride-containing environments where ordinary laboratory pH electrodes may not be suitable. The PP body improves chemical resistance, while the ceramic junction and Longlife reference system support stable measurement behaviour in demanding analytical procedures.
PRO6151 uses an S7 connector. For meters with a BNC input, an appropriate S7-BNC(Q9) cable should be selected. Meter compatibility, cable configuration and application suitability should always be confirmed before ordering.
Key features
- HF-resistant pH composite electrode for hydrofluoric-acid titration applications.
- PP body for improved chemical resistance in aggressive media.
- Ceramic junction for stable liquid junction behaviour.
- Longlife reference system for reliable routine titration workflows.
- pH range 2–11 for selected acid titration and chemical analysis procedures.
- 3 M KCl fill solution for the reference system.
- S7 connector for use with suitable S7 input or S7-BNC(Q9) cable.
Suitable for
- Hydrofluoric acid titration and fluoride-containing sample workflows.
- Chemical processing and analytical laboratories handling aggressive media.
- Metal finishing, etching and surface treatment laboratories.
- Routine pH monitoring where HF compatibility is required.
- Replacement electrode setups requiring S7 electrode connection.
- Laboratories that need a PP-body electrode instead of standard glass-body electrodes.

Applications and laboratory value
HF acid titration
PRO6151 is intended for pH measurement in selected hydrofluoric acid titration workflows where a PP-body HF-resistant pH electrode is required.
Aggressive chemical media
The PP body, ceramic junction and Longlife reference system make the electrode suitable for demanding samples where standard glass pH electrodes are not ideal.
Analytical laboratories
The electrode supports laboratory workflows in chemical analysis, metal finishing, surface treatment and controlled titration procedures.
Replacement electrode selection
PRO6151 is relevant when the method requires an HF-compatible pH electrode and the selected pH meter can accept an S7 electrode connection or suitable S7-BNC(Q9) cable.
How to choose the correct pH electrode for HF acid titration
When selecting the PRO6151 pH electrode HF acid titrate, the complete measurement setup should be checked, not only the pH range. Confirm the pH meter model, input connector, cable arrangement, sample composition, HF concentration, titration method, working temperature and routine calibration procedure before ordering.
COLO.Science can help match PRO6151 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.
PRO6151 pH electrode HF acid titrate for demanding laboratory titration
The PRO6151 pH electrode HF acid titrate is a specialised electrode for laboratories that need pH measurement in hydrofluoric acid titration and aggressive chemical sample workflows. The PP body helps improve resistance in HF-containing media, while the ceramic junction, Longlife reference system and 3 M KCl fill solution support stable electrode operation when the electrode is correctly selected, calibrated, stored and maintained.
In daily use, the quality of pH measurement depends on more than the electrode specification. Buffer freshness, calibration frequency, sample temperature, cable condition, meter input format, electrode storage and the selected analytical method all influence stability and repeatability. PRO6151 provides a compact HF-resistant pH electrode platform, while the final laboratory setup should be defined as a complete pH measurement system.
