Invensys Operations Management has released the latest version of its Foxboro PH12 Series sensors. These precision electrochemical sensors are used with a popular set of mounting accessories to measure pH and ORP and provide a unique electrode technology in the widely used 12 mm form factor. They are rugged, easy-to-use devices particularly well suited for low and high temperature installations and provide fast response, long life, high accuracy and stability. The low cost construction renders the sensor disposable, and therefore eliminates costly sensor maintenance.

Unlike other 12 mm pH sensors, the Foxboro Model PH12 incorporates a chemical resistant PEEK body, flat membrane sensing electrode and no metallic wetted parts. This combination of features, together with temperature ratings of 125 C (flat glass) or 140 C (domed glass), provides unrivaled ruggedness and length of service life. The Foxboro Model PH12 Series Sensor is also longer. New lengths include 225 mm (8.9”), 360 mm (14.2”) and 425 mm (16.7”). In addition, the PH12 incorporates a nonmetallic solution ground as a standard feature, allowing for sensor diagnostics in a cost effective platform.

Key capabilities:
•   Durable PEEK body
Excellent strength and chemical resistance; longer service life; better resistance to the rigors of maintenance;
•   Best performing flat membrane electrode
High temperature capability to 125°C greatly expands the range of applications for flat glass; rugged construction extends service life in the harshest of applications;
•   Non-metallic wetted parts
Immune to attack from most process fluids, greatly extending the service life;
•   Wide range and high temperature electrodes
Domed glass electrodes for very wide range (-25 to +125 C) and very high temperature (140 C) allow optimization of sensor type for specific applications;
•   Biocompatible and 3-A Sanitary Compliant
Certified for use in food, beverage, dairy and biopharmaceutical processes that require strict compliance with applicable standards.
