DULCOTEST PHEF 012 SE

Description
  • Electrochemical combination electrode: pH and reference electrode integrated
  • Optimized pH glass for use in the presence of glass-corroding hydrofluoric acid (HF). HF forms primarily in the presence of fluoride (F-) at a pH 4. Glass corrosion is favored by increasing fluoride concentration, decreasing pH, and increasing temperature. The glass composition and structure of the PHEF type reduce the release of SiF4. Extended lifetime in the presence of fluoride (F-) at a pH 7
  • Twist protection of the connected sensor cable. This allows the cable to remain connected when installing and removing the sensor, and prevents troublesome moisture at the plug contacts
  • Flat shape of the glass diaphragm and large annular diaphragm allow use in polluted water that also contains abrasive solids
