The versatile Q45P system monitors Potential of Hydrogen (pH). Measurement and control of pH is important in a wide variety of industries. Water and wastewater, boiler feed water, food processing wash water, chemical plant make-up water and many other aqueous systems require reliable pH monitoring. The pH Transmitter provides the combination of durability, accuracy, and versatility required for virtually any pH monitoring application.

Q45 pH transmitters use “differential” type sensors designed for long life in the most demanding applications. Differential sensors are well suited for applications that quickly poison conventional pH or ORP sensors and can be easily serviced by operators. A variety of sensor styles are available to meet almost any application.
