pH & ORP Sensor for Brine


The Turtle Tough pH & ORP Sensor for Brine has a long history of success in applications where high brine levels are present. Saturated Sodium is brutal on pH sensors, specifically attacking the glass and significantly reducing sensor life. By utilising our specially formulated sodium resistant glass we can ensure superior accuracy, stability and longevity.

  • Available as a TOUGH analogue or Smart digital sensor
  • Proprietary saturated sodium resistant glass
  • Acid/Fluoride, Ammonia, Chlorine and Sulphide Gas Resistant
  • 0 to 11 pH Range
  • -5°C to 105°C
  • Immersible, Submersible if threaded on sealed immersion rod with sufficient sealing tape

The TT-Na-pH Sensor utilises the highly chemical resistant RYTON body plastics with a 1" MNPT back end thread or front end 3/4" thread. For fully submersible applications this can be threaded onto our stainless steel immersion rod assembly, or supplied with optional extreme waterproofing. The standard HDPE reference provides a very fast response. Alternatively the high capacity double junction KYNAR reference provides exceptional resistance to sulphides and other dissolved gasses.

Digital Sensor Technology (-D)

This sensor is available with our digital smart sensor technology. This plug and play sensor has a quick connect fitting, eliminating the need for hard wiring to the analyser. Onboard sensor memory allows the storage of calibration data, analyser configurations and sensor service history. This allows the sensor to be conveniently maintained and calibrated off-site or in the laboratory and pre-programmed with calibration data and analyser configurations. This stored information automatically uploads to the analyser upon connection and eliminates the need for any interaction with the analyser, greatly simplifying the change-out of sensors. A service log stored on the sensors is ideal for maintenance and quality assurance records.

  • Designed Specifically for Brine
  • 6m cable
  • RYTON with 3/4" Front End & 1" MNPT Back End
  • Fast Response Polypropylene Reference
  • Digital Sensor Technology (-D) (optional)
    • No hard wiring – plug-n-play connectivity
    • Sensor stores calibration data, analyser configuration and sensor history
    • Hot-swap for quick sensor change-out
    • No interaction with analyser – sensor data auto uploads
