Chemetrics® K-2505 Free And Total Chlorine Test Kit With Plastic Case, Range: 0-1 And 1-5ppm, DDPD Method, To Complete 30 Tests

This free and total chlorine test kit has a range of 0-1 and 1-5ppm and uses the DDPD method. It comes in a plastic case and contains everything needed to perform 30 tests: refill, low and high range comparators, activator solution, neutralizer solution, 25mL sample cup, instructions, and MSDS. Because of its strong oxidizing properties, chlorine is an excellent biocide used to treat potable waters, municipal wastes, and swimming pools. When used to treat potable water, chlorine helps alleviate the adverse effects of iron, manganese, ammonia, and sulfide. The DDPD method is derived from the DPD method. Test kits that employ this chemistry are well suited for use where biocides and chromate corrosion inhibitors are used simultaneously. DDPD reacts with free chlorine to form a purple product. When ammonia or amines are present in the sample, some of the chlorine may exist as combined chlorine. To determine total chlorine (the sum of free and combined), use the A-2500 Activator Solution (potassium iodide) that is supplied in the kit. Results are expressed as ppm (mg/L) CL2. Chemetrics® DDPD method is also applicable to the direct determination of hypochlorite concentrations in various cleaning preparations and disinfectants prior to their dilution. The DDPD compound reacts with hypochlorite ions to form a purple color. Results are expressed as percent (%) NaOCl. Test: Free And Total Chlorine. Range: 0-1 And 1-5ppm. Method: DDPD. MDL: 0.05ppm. Low Range Comparator: 0, 0.1, 0.2, 0.3, 0.4, 0.6, 0.8, And 1.0ppm. High Range Comparator: 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, And 5.0ppm. Number Of Tests Per Kit: 30. Chemetrics® #: K-2505.
