About this item
Comparator test kit employs diethyl-p-phenylene diamine (DPD) indicator in convenient tablet form to measure the various factors of water chlorination
The DPD No. 1R tablet measures free chlorine, the DPD No. 3R tablet shows dichloramine content and total chlorine level, and the DPD No. 4R tablet contains reagents needed for one-step reading of total residual chlorine. Drop a single tablet in the test sample and compare the resulting color reaction against the permanent color standards in the comparator. Color standard values are 0.2, 0.4, 0.6, 0.8, 1.0, 1.5, 2.0 and 3.0ppm chlorine.
