The Rosemount™ 372 Hydrofluoric Acid (HF) Resistant pH Sensor is built for environments where standard pH sensors quickly fail.
Its specialized fluoride and acid resistant glass dramatically reduces HF attack, extending sensor life and minimizing maintenance. A double junction, poisoning ion resistant reference cell maintains measurement stability, while a chemically durable Ultem™ body ensures long term performance. With flexible ¾ inch MNPT forward and 1 inch MNPT rear connections, the sensor supports both insertion and submersion installations. Ideal for semiconductor etching baths, fluoride rich wastewater, and other aggressive chemical processes, the Rosemount 372 delivers reliable accuracy, longer service life, and reduced downtime—enabling tighter, more confident process control.
