Configurations      Dimensions     T & P Ratings

  • Kynar (PVDF) hot tap pH sensor for the most aggressive chemical applications (No wetted metallic components)
  • Proprietary low-noise, high temperature signal cable
  • Patented Axial Ion Path® reference technology increases electrode lifespan in harsh applications
  • Proprietary low-noise, high temperature signal cable
  • Specialized glass formulations
  • Universally compatible with all manufacturer's analyzers
  • (Actual Sensor color is white)

For harsh chemical applications the insertion style 567 pH / ORP sensor provides a unique hot tap solution. The sensor requires no metallic sheath; instead a Kynar (PVDF) sensor body provides structural integrity and protects against exposure to chemical attack. The Kynar body combined with the Axial Ion Path™ reference and multiple glass electrode options make for a sensor well suited for strong acids, high caustic concentrations, and other industrial pH measurement applications where corrosion is an issue.
