HACH compatible pH & ORP Sensor


The Turtle Tough HACH compatible pH Hach pH & ORP Sensor is an analogue sensor that is compatible with most Hach Analysers that have an analogue input.

  • HACH Compatible pH & ORP Sensor
  • Outlasts OEM by up to 10 times
  • Extreme slurry/abrasion resistant (optional)
  • 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 gases. 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 Hach Analysers.
