Sodium hypochlorite, aka chlorine bleach, is widely used in the dairy industry, including cheese production, primarily as a sanitizing agent. Monitoring its concentration is crucial to ensure food safety, quality control, and regulatory compliance.
Dairy facilities use 50–200 ppm sodium hypochlorite solutions for sanitization. Indigo® 0-300ppm "fast take" chlorine test strips give results in <10 seconds & meet global food safety initiatives for microbiological standards of food production by accurately measuring free chlorine availability even down to residual levels. See Specifications below.
Surfaces and equipment must be thoroughly rinsed before milk comes into contact. Regular testing of rinse water & equipment ensures chlorine is within safe levels.
All Indigo® chlorine bleach (sodium hypochlorite) test strips have a 3 year minimum guaranteed shelf life & come with a Certificate of Analysis, Stability & SDS documents listed below; Certificate of Conformance on request. Be prepared for any health & safety audit or inspection.

The high chlorine test strips are handy for operators to measure Free Chlorine levels to ensure adequate dosages have been achieved when disinfecting watermains and cleaning storage facilities. They arrived very quickly.
I am glad these are packaged in a container; we have had some in the past packaged in a paper envelope (from another company), which is hard to keep dry. They work just as advertised - the only imperfection for us is that the colors are fairly similar and it can be hard to tell at a glance what the result is. Otherwise, great.
Thanks for the feedback. The packaging for most sanitizer test strips come in special desiccant lined containers which is explained further in: Test Strip Expiration Dates; Good Today, Dead Tomorrow?
Some of the color charts are indeed harder to read than others. Good lighting can help. Fluorescent lighting is not as contrast friendly as natural sunlight or halogen or quartz.
Interesting applications, thanks for the feedback.
