Monitor hydrogen peroxide and peracetic acid concentrations easily

The membrane-covered, amperometric sensors measure the concentration of hydrogen peroxide or peracetic acid in aqueous solutions. Typical application areas include electroplating plants, dairies, swimming pools, and the chemicals industry.

The sensors are not suitable for detecting the absence of peracetic acid or hydrogen peroxide.

Depending on the type, the electronics integrated in the sensors provide a temperature-compensated
current signal (4 to 20 mA) or a Modbus RTU output signal.

The sensors can be connected directly to indicating devices/transmitters/controllers. They supply the sensors with voltage and allow for easy calibration of the measuring system.
