DULCOTEST PHEF 012 SE
pH sensor for use in measuring medium containing fluoride
pH sensor optimised for use with acidic water containing fluoride and abrasive water containing solids at up to 50 °C/7 bar.
We currently only offer an extract from our product portfolio, other variants are available on request.
Send Request- Electrochemical combination electrode: pH and reference electrode integrated
- Optimised pH glass for use in the presence of glass-corroding hydrofluoric acid (HF). HF is formed primarily in the presence of fluoride (F-) at a pH of < 4. Glass corrosion is promoted by a constant concentration of fluoride, a falling pH value and a rising temperature. The glass composition and structure of the PHEF type reduce the release of SiF4. Extended service life in the presence of fluoride (F-) at a pH of < 7
- The flat shape of the glass diaphragm and large ring diaphragm facilitate use in contaminated water, which also contains abrasive solids
