ATI's new portable Series PQ45 answers the need for a field-deployable monitor capable of measuring and recording water quality data in a variety of operating environments. It is ideal for short-term recording of specific parameters such as Free Chlorine in potable water. The systems are available for monitoring various components in water. The available measurements are dissolved oxygen, free & combined residual chlorine, dissolved ozone, residual chlorine dioxide, conductivity and pH or ORP. Each PQ45 system is supplied ready to use for the parameter specified. If systems are to be used for free or combined chlorine, dissolved ozone, or chlorine dioxide, a second measurement of pH can be added to the system.

Chlorine monitoring

Pennwell web 200 257

The Rosemount Analytical Model TCL from Emerson Process Management is a reagent-based system for measuring true total chlorine in water. Ideal applications are the analysis of drinking water and reclaimed wastewater. The reagent, potassium iodide dissolved in white vinegar, is inexpensive and needs replacing only every other month. Sample flow requirement is less than six gallons per day, a real advantage in places where drainage is limited or water is scarce and can't be wasted.
