HI 3898
Chloride Rapid Screening Test for COD – ISO and EPAProduct Description:This screening test is a quick test to detect high chloride levels in water and wastewater that might cause interference with official COD methods. The test is in accordance with the ISO 15705:2002 method, and indicates within seconds a YES/NO possibility of having chloride interference on COD measurements. The kit can be used for checking 1000 ppm chloride concentration for the ISO COD testing, or for a 2000 ppm chloride check for the USEPA, APHA, AWWA and WEF methods.

Upon adding the indictor to the sample, the solution turns yellow. Then the chloride titrant is added and a white precipitate is formed if chlorides are present. If the chloride concentration is lower than 1000 ppm for ISO, or 2000 ppm for EPA, a orange-brown complex is formed. If the solution remains yellow, high chloride concentrations are present.

Order Information:

HI 3898 test kit comes with 25 mL chloride titrant bottles (4), 7 mL chloride indicator, glass cuvette with plastic stopper and1.0 mL calibrated syringes with tips (2).
