RPC’s Ultra-Low™ Total Chlorine Test Strips were designed and developed specifically for testing very low levels of chlorine and chloramines (TC) in water. Each test strip is individually foil wrapped and has a patented flow-through aperture. These features assure strip stability and maximum sensitivity. Seven color blocks with yellow-to-blue color shades make it easy to differentiate between values. RPC’s Ultra-Low™ Total Chlorine Test Strips provide easy testing for ppm values of 0.0, 0.01, 0.02, 0.05, 0.1, 0.2, and >0.2. Use of a special, non-DPD reagent eliminates manganese interference that has caused problems for DPD tests. Use RPC’s Ultra-Low™ Total Chlorine test strips to be confident that chlorine levelsin your water do not exceed maximum levels called out in your procedures.
