Chlorine Test Strips, Sodium Hypochlorite Solution Test Papers, Bleach Test Paper, 100 Strips, Range 50-2000PPM

No complaints, clean packaging

Taste is excellent, sodium not quite so high. I use less and like it more.

They say to dip and then read immediately but they get darker the longer they sit

My favorite test papers for home-made HOCl (hypochlorous acid). They have a wide detection range, easier to see the difference than other brands.I typically use ~1/3 strip at a time & use tweezers to dip.

The test paper guide is not color correct. The 500ppm is supposed to be dark rose and the 1000 is supposed to be maroon. I ran my electrolyzer several cycles. The color always stayed orange but more intense/darker orange.So, instead look at the examples on this seller's site. Even their high ppm examples look orange instead of matching the guide.Next time I buy, I'll try a different brand.

I feel sheepish that I used this incorrectly and assumed it didn’t work. The test papers come in tiny little booklets with a blue cover and a thin white paper strip to protect the actual test papers. Thank you for the awesome customer service that reached out and clarified this for me. They work great!

I couldn't get them to work. Never changed colors.

These did not react at all to well water but did react to pool water. Thats what they should do.They are a bit small for my fat fingers, but I can make it work.They include a little clear plastic box to keep them dry.
