Overview

Open amperometric probes offer stable and accurate measurements to determine chlorine concentration. They exploit the potential difference that is created between a pair of electrodes, one copper and the other platinum, when they are crossed by a stable flow of water in which chlorine ions are present. This type of cell is normally positioned by creating a “by-pass”, in parallel to the main pipeline of the process, and making sure that it is crossed by a constant flow which, to ensure the best measurement quality, must be stabilised around 60 l/h.

The modular system created by Mytho (covered by an industrial patent) consists of an amperometric cell that can be mechanically coupled to other probe-holder modules, intended to house probes for pH, ORP and temperature along with potentiostatic probes for the determination of other substances.
