I got this to test the ph of my HOCL machine output. Seems to verify that I haven’t made bleach. I don’t have a comparison to check accuracy, but I am happy.

Super simple/easy to use. Used it to test level of Chlorination for a holding tank treatment. Gave us confidence that we shocked our tank at the right level. Results are that we have tested bacteria free since using these strips in our treatment.

We are required to have water testers for licensing. These have a long shelf life and are the best value for the money.

Used these for a fundraiser to show disinfectant strength of solution for Dept. Of Health inspection. Easy to read. Recommend highly.

Its hard to tell exactly which one goes to what level. We had to get to a minimum of 500 ppm. We purchased the Ultra High strips as well 0-750 and want these 0-2000 as a confirmation that we had hit our minimum. We were testing at 8-10 locations over the period of an hour, comes with 50 strips, worked great. This range is way outside our equipment's capability to measure chlorine.

This product was easy to use and very informative! It helps distinguish between disinfectant and sanitizing, right now with everything happening that is very important!

I bought these for use in my daycare, but after receiving them on 12/14/22, they turned yellow by 2/1/23. The expiration date on the bottle shows 5/2025. I tested them with other testing strips and they were not reacting correctly.
