Turtle Tough HACH-pH Hach pH Sensor

The TT-HACH-pH Hach pH Sensor is an analogue pH sensor that is compatible with most Hach Analysers that have an analogue input (even digital models). 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 KYNAR 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 Hach Analysers.

The sensor can also be ordered with an optional integral differential preamplifier that supports a range of unique Turtle Tough features including:

  • Extreme slurry/abrasion resistant
  • Ultra Tough unbreakable glass
  • Zinc resistant
  • High HF acid resistant glass
  • Quick disconnect cable plugs
  • Extended cable runs up to 100m
