PNL S507-CAC – Panels with CAC Probe, for Water Disinfection


STEIEL offers a wide range of “turnkey” solutions, including instrument and measurement sensors assembled on panel.

The more complex systems are also equipped with an adjustment dosing pump and / or data recording / managing device.

This series has been designed for the analysis (and control) of disinfectant concentration in water, with a membrane closed amperometric cell, which – depending on model – allows to measure the level of chlorine (active, available, total; even in sea water), chlorine dioxide, bromine, peracetic acid, chlorite, ozone, hydrogen peroxide.

These systems are widely used in the purification, sanitation and continuous disinfection of water distribution systems and networks.
