Q45/79 Chlorine Monitor Manual

While chlorine has become the most widely used disinfectant in the world, there are still some applications where monitoring chlorine residuals can present a challenge. Multiple forms of chlorine in drinking water, wastewater effluent, and cooling tower water require a Total Chlorine measurement to ensure that all chemical species are quantified. In some cases, the chlorine concentration is quite low and often below the detection limits of conventional monitors.

ATI has developed a new total residual chlorine monitor with improved sensitivity and zero stability to meet these applications. The Q45H-79 Total Chlorine Monitor from ATI uses standard EPA approved iodometric chemistry where, by addition of buffer and potassium iodide, the various chlorine compounds in solution react to form iodine. The iodine released in this reaction is measured using a highly sensitive amperometric sensor capable of 1 PPB sensitivity. The output of this sensor is linear with respect to concentration and provides fast response for both upscale and downscale concentration changes.

Q45H-79 water quality monitors by ATI are available in two versions,one that includes all components conveniently integrated into a NEMA 4X fiberglass enclosure, and a second that separates the monitor from the chemistry system for applications where a more convenient display location is desired. A sample inlet filter assembly attached to the side of the enclosure allows filtered sample to be drawn from the inlet flow. Sample must be pumped to the inlet assembly at a rate high enough to insure the desired response time for the measurement system. Excess sample is bypassed to any convenient drain location.
