Transmitter AMU-II pH/Redox

The AMI-II pH/Redox transmitter provides continuous, simultaneous measurement of pH or Redox (ORP) potential in potable- boiler-, process water, return condensates and effluents. Designed for real-time water quality monitoring, it ensures precise, reliable data to support water treatment and effluent control processes. The transmitter features one sensor-, temperature- and flowmeter input, with the latest technology.
