The strips do work on a basic level. Sometimes that’s all you need
We were having water issues so these were purchased. They seem to work. I don’t have a lot of experience with water testing. It worked.

Works well for testing HOCL machine output
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.

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

Works as advertised
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.

Ultra High II is to 2000 ppm
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.
