Versatile pH/ORP electrode with refillable reference system and integrated temperature sensor

  •  Refillable reference chamber enables the use of specific electrolytes to suit specific applications 
  • Open reference design allows for up to 10 bar overpressure (up to 145 psig) 
  • Triple ceramic diaphragms resist fouling in harsh industrial conditions 
  • Durable 0-14 pH sensitive glass can withstand CIP treatment and operating temperatures up to 130 °C (266 °F) 
  • Pt 100 or Pt 1000 RTD in Model OPS41 pH electrode increases measurement accuracy at extreme temperatures 
  • ORP sensor has platinum ring electrode as standard 
  • NEMA 6 rated detachable cable system provides the convenience of a quick connect with the reliability of a fixed cable 
  • Each electrode is serialized and performance tested at the factory
