"Reagentless” Residual Chlorine Monitor The Q46H Residual Chlorine Monitor is available in two versions, a free chlorine monitor for potable water, and a combined chlorine monitor ideally suited for chloraminated water. The Q46H measures chlorine directly, and does not require the addition of chemical reagents, so there are no moving parts that need to be maintained. The chlorine measurement does not alter the sample, so the water flow can return to the system, if desired. Using the optional pH sensor, the Q46H will automatically correct for changes in process pH, maintaining an accurate free chlorine measurement. The pH sensor option also provides an additional analog output that can be assigned to pH, converting the chlorine monitor into a two parameter system, providing isolated 4-20 mA outputs for chlorine, pH and temperature. The pH sensor option is available with either the free chlorine or the combined chlorine monitors.
