Foxboro compatible pH & ORP Sensor

Foxboro compatible pH & ORP Sensor


The Foxboro compatible pH & ORP sensor for OEM replacement uses our true differential pre-amplifier sensor that mates seamlessly with Foxboro analysers. 



  • Foxboro compatible pH & ORP Sensor
  • RADEL with ¾” MNPT Front-end & 1" MNPT Back-end
  • -5°C to 105°CHigh capacity
  • Polypropylene Reference
  • 6m Cable (Analogue Only)
  • Coat Resistant Materials Reduce Fouling
  • Acid/Fluoride Resistant
  • Ammonia, Chlorine and Sulphide Gas Resistant
  • Immersible, submersible if threaded on a sealed immersion rod with sufficient sealing tape
  • Double junction 
  • Differential preamplifier
  • Proprietary toughened glass

The Foxboro-compatible pH & ORP sensor is made possible by utilising our true differential preamplifier sensor that mates seamlessly with Foxboro analysers. Foxboro analysers have a long history in industrial process measurement. As a result, some of the most resilient sensors we've designed are compatible with Foxboro hardware, and virtually all our application-specific sensors can be designed to interface with these analysers.

Our replacement OEM sensor for the Foxboro product is designed as an affordable all-rounder and can be special ordered with nearly any option. The standard double junction sensor is sulphide resistant.

This OEM replacement is not simply a substitute. It will outlast and outperform the OEM product several times over. 20 years of evidence guarantees it. Extreme dehydration, slurry/abrasion resistance, and high HF are all options supported by this sensor.

The result is a sensor that will outperform, every time, the OEM because of our application-specific approach to improved sensor performance.  There are many good reasons why some of the biggest names in the industry are using Turtle Tough sensors on a Foxboro analyser, but the main reason is reliability and a lower cost of ownership.

Recommended Applications

  • Industrial Chemical
  • Food & Beverage
  • Semiconductor
  • Pharmaceutical
  • Wastewater

Any measurement where aggressive chemical cleaning is needed to remove fouling or low-maintenance operation is required with minimal cleaning and re-calibration.
