The Model TCL is a sample conditioning system that permits a single sensor to measure total chlorine in water. The sample conditioning system continuously injects a solution of acetic acid (vinegar) and potassium iodide into the sample. The acid lowers the pH to between 3.5 and 4.5 and allows total chlorine in the sample to quantitatively react with the potassium iodide to produce iodine. The sensor measures the iodine concentration, and the analyzer displays the total oxidant concentration in ppm as Cl2.

The Model TCL can also be used to measure chlorinated seawater. Seawater contains about 50 ppm bromide. When chlorine, as sodium hypochlorite or chlorine gas, mixes with seawater, the chlorine reacts with bromide to form a mixture of bromine oxidants, primarily hypobromous acid. In the TCL, the hypobromous acid readily oxidizes iodide to iodine.
