Description product group
  • Electrochemical combination electrode: ORP and reference electrode integrated
  • Diaphragm and reference system optimised for use in swimming pools and for potable water
  • Ceramic diaphragm with special material, optimised size and optimised pore diameter
  • Long service life due to reduced diffusion ('bleeding') of the electrolyte
  • Long service life due to the material, which is inert to aggressive disinfectants
  • Stable reference system
  • Rotating sensor head sleeve. This means that the cable can remain connected during installation and dismantling of the sensor, avoiding moisture on the plug-in contacts
  • Lead-free glass for advanced and environmentally-friendly production, use and disposal (RoHS-compliant)
