Portable handheld colorimeter LH-C01 can test residual chlorine ion concentration in the water.It can detect and analyse the sample very fast by only three steps:start,zeroing and reading with small capacity(only 220 with battery).
Method：DPD method，residual chlorine react with the DPD reagent，the color of the sample change to be red.
Operating conditions:0 to 40℃,0 to 90% relative humidity (noncondensing)
Life of battery：1×9V,more than 40h
shutdown：Press the “ON/OFF” button to shutdown the colorimeter after the test.
The Total Residual Chlorine measurement in your effluent hasn’t changed, but disinfection rates have dropped sending E. coli results over the permit limits. If the chlorine residual in the effluent produced good disinfection results one day, why not the next?
Determining the cause of this type of problem will require an understanding of what chlorine residual really is and what it is not. When we measure for Total Residual Chlorine (TRC) in wastewater we are not determining actual chlorine atom concentration in the way we would determine, for instance, copper concentration. The measure we make is more of a reactive form of chlorine concentration than anything specific.
