PH12 | Foxboro by Schneider Electric


Foxboro by Schneider Electric Manufacturer LogoThe Foxboro® brand PH12 Series Sensors are precision electrochemical sensors that are used with a popular set of mounting accessories to measure pH and ORP. These sensors provide a unique electrode technology in the widely used 12 mm form factor, and provide fast response, long life, and high accuracy and stability. They are rugged, easy-to-use devices particularly well suited for low and high temperature, sanitary, and biocompatibility installations. The low cost construction renders the sensor disposable, and therefore eliminates costly sensor maintenance.

Featured Highlights

  • Proprietary electrode glass formulations.
  • Double junction reference using Nafion ion barrier.
  • Fast thermal response; <1 minute for 80% step.
  • PEEK or Borosilicate Glass sensor bodies.
  • Variopin connector integral to sensor body.
  • A selection of electrode types offered:
    – For pH measurement: Domed glass electrode to 125 or to 140°C (to 257 or to 284°F); or flat ruggedized glass electrode to 125°C (to 257°F).
    – For ORP measurement: Platinum electrode to 125°C (to 257°F).
    – For combination (simultaneous) pH and ORP measurement: glass and platinum electrodes to 125 or to 140°C (to 257 or to 284°F), depending on glass electrode selected.
  • Sanitary sensors comply with 3-A Standard 74; also meet FDA food processing industry requirements.
  • Sensors meet the biocompatibility requirements of EN ISO 10993-5 and USP 87.
