Endress + Hauser replacement pH / ORP Sensors

Endress + Hauser compatible pH & ORP Sensor


The Turtle Tough Endress & Hauser compatible pH & ORP sensors are the perfect replacement sensor for your E&H Analyser.  They are built for tough applications and will outlast the original equipment by to 10 times. 

  • Endress & Hauser compatible pH & ORP Analogue Sensor
  • Outlasts OEM by up to 10 times
  • High Capacity Polypropylene Reference
  • Acid/Fluoride, Ammonia, Chlorine and Sulphide Gas Resistant
  • 0 to 14 pH Range
  • -5°C to 105°C

For more than 20 years our OEM replacement sensors have provided our customers with superior performance over the original product in virtually every aspect. The chemical and physical resistance provides a superior service life of up to 10 times that of the OEM product. In nearly all cases our customers report less drift and significantly less maintenance and the reason they keep using Turtle Tough… a significantly lower cost of ownership.

The high capacity solid state polypropylene reference junction provides superior chemical resistance to sulphides and other dissolved gasses. The standard sensor utilises a double junction, however, a triple junction is available as a special order. The sensor is built with PT1000 integrated temperature compensation element so that it interfaces seamlessly with the E & H Analysers.

For extreme applications that require our extreme slurry/abrasion resistant, zinc resistant, or High HF resistant glass a different analyser will need to be considered.

  • 6m Cable (Analogue Only)
  • RYTON with 3/4" MNPT Front & Back End
  • Double Junction (Triple optional)
  • Coat resistant materials reduce fouling
