Hanna Instruments, HI 3898: Quick Chloride Test

Quick Chloride Test

• Important for COD Analysis
• Simple Yes / No Test
• ISO Compliant

The HI 3898 test kit, developed according to the ISO 15705:2002 method, determines chloride concentration. This test is very important and recommended by ISO, as an excessive presence of chloride can interfere with the COD official analysis method. The test gives a fast YES/NO reply to the question if chloride interferes with COD analysis, i.e.: if chloride concentration is greater than the official maximum level, the solution turns yellow and the sample needs to be diluted before performing the COD test, otherwise if the solution is orange-brown, the sample doesn't need to be diluted. The maximum level allowed is 1000 ppm of Cl-following ISO methods, or 2000 ppm of Cl-for US EPA, APHA, AWWA and WEF methods.

HI 3898 is supplied complete with instructions.
