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.
