Total Chlorine Monitor

The only monitor that works in dirty applications

ATI Model (A15/79)

The total chlorine monitor is an online system that provides the components to perform total residual chlorine measurement reliably and accurately.

There are three separate components:

  • Chemistry Module – where buffer and potassium iodide are added for measurement
  • Inlet Flow – assembly where raw sample is delivered to the system
  • Electronic Readout – containing the chlorine concentration display, analog output, and alarm contacts (available in general wall mount or NEMA 4X).

How it works:

A small amount of sample is pumped into the system and mixes with pH 4 buffer, and then with potassium iodide.

The air stripping system, used for highly contaminated samples, brings the reacted sample to an air-stripping chamber where the released iodine is stripped from the sample, with the resulting air stream directed to the iodine gas sensor located in a separate chamber.

It is ideal for low range measurement of dechlorinated wastewater, where biological growth from sulfur reducing bacteria can cause severe fouling problems in contact systems.

Features and Benefits:

  • Gas Phase Sensing: Measurement is made in gas phase without contact between sample and electrodes, eliminating the potential for sensor fouling.
