Description product group
  • Electrochemical combination electrode: pH and reference electrode integrated
  • Diaphragm and reference system optimised for extremely high solids content
  • The solid electrolyte makes the diaphragm redundant and prevents the reference system from becoming blocked up
  • Long service life when sludge is present due to lack of a diaphragm
  • Long service life as the solid electrolyte prevents the electrolyte from 'bleeding'
  • Stable reference system
  • Twist protection for the sensor cable connected. This means that the cable can remain connected during installation and dismantling of the sensor, avoiding troublesome moisture on the connector contacts
  • Lead-free glass for advanced and environmentally-friendly production, use and disposal (RoHS-compliant)
