Product Details & Documents

These electrodes are low maintenance sensors for heavy duty process applications in the chemical industry. They are ideally suitable for measuring media with extreme ionic strength - whether boiler feed water or brine - also in strongly oxidizing acid and alkali containing media.

  • Low-maintenance electrodes: no electrolyte topping up or installation of complicated pressure sequence control required
  • Pinhole diaphragms, so reference electrode is not polluted or blocked
  • Duralid electrolyte with high KCl content combines very long working life with rapid and stable measurements
  • Proven H membrane glass with very low alkali error and optimized spherical shape
  • Integrated pressure compensation cushion

PL8× models
Reference system: Duralid solid electrolyte with a high KCl content
Diaphragm: 2-hole

PL9× models
Reference system: RheoLid electrolyte with KCI storage rings
Diaphragm: PTFE
