Chloride Water Testing Kit, Measurement range: 0-500 mg/L

Chloride is the most common inorganic anion in water and wastewater, and often found as a component of salts. Common salts are calcium chloride (CaCl2), potassium chloride (KCl), and sodium chloride (NaCl). Natural sources of salt include the ocean and various salt deposits. Chloride can also enter water through more industrial sources like agriculture runoff, road salting, wastewater effluent, and industrial wastewater. The Maximum Secondary Contaminant Level in drinking water for chloride is 250 mg/L. The visual Chloride in water test kits utilize CHEMetrics Titrets® ampoules. Titrets ampoules use a reverse titration technique to measure analyte concentration levels (titrant volume inside the ampoule is fixed while the sample volume is varied). After snapping the ampoule tip, sample is drawn into the test ampoule in small doses until a color change signals the endpoint has been reached. The titration is stopped at the end point, and the liquid level in the ampoule corresponds to the concentration printed on a scale on the ampoule's outer surface. Titrets can measure four different ranges (see below), and all use the mercuric nitrate chemistry for analysis. The instrumental kit utilizes CHEMetrics Vacu-vials® ampoules and ferric thiocyanate chemistry in testing for chloride. This test kit requires a CHEMetrics direct-readout photometers or a spectrophotometer capable of accepting a 13-mm diameter round cell.
