pH monitor

The ATI pH monitor provides the combination of durability, accuracy and versatility required for most pH monitoring or control applications. Differential or conventional sensor options, as well as an automatic sensor cleaning system.

Measurement and control of pH is important in a wide variety of industries. Water and wastewater, boiler feed water, high purity water, food processing wash water, chemical plant cooling water and many other aqueous systems require reliable pH monitoring.

The ATI pH monitor has an optional third analog output or an additional bank of low power relays. Digital communication options include Profibus DP, Modbus RTU, or Ethernet IP variations.

ATI’s Q-Blast option provides the ideal answer for automatic pH sensor cleaning. Employing a unique “air-blast” cleaning method, sensors can be cleaned as often as necessary without operator attention. Pulses of pressurized air delivered through a nozzle at the tip of the sensor remove accumulated solids from critical sensing surfaces, resulting in accurate and reliable measurements.

Differential sensors provide reliable, long lasting service in demanding applications while conventional sensors provide a lower cost alternative for clean water applications.
