Chloride is found in nearly all natural waters and affects human taste above 250 mg/L. High levels inhibit plant growth, and many industrial processes need to limit chloride concentration. With Hach's chloride test strips, technicians in the field can test many samples in only a few minutes and make immediate evaluations on-site, without any measuring, set-up, clean-up, or chemical handling. Our chloride test strips are also used in laboratories all over the world for pre-test screening- to detect the presence of materials that might interfere with lab testing.
