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.

Interesting applications, thanks for the feedback.

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.
