Professional Hydrion Chlorine Test Strips CH-1000, Range 0-1000 100 strips

Works great for testing my home generated HOCl to make sure it’s the strength I need, and to see how long it lasts until it degrades. Quick results, easy to read. I cut the strips in half long ways to get double the use from them- just a tip that I was given that I’m passing on, as they are still pricy.

This is the most easiest to read and most accurate chlorine test strip. I would highly recommend it for daycare’s that use a sanitizer and disinfectant made of chlorine and water.

Great product. I'm using it to test my hypochlorous acid.

I use these for making homemade hypochlorous acid, and testing the ppm after making a batch. I love that they go all the way up to 1000 ppm. It is definitely worth the extra money to purchase these versus testing sticks that only go up to 200. Because these are pricier, I cut them in half when I’m testing my batches of hypochlorous acid.

The colors between 250 ppm and 500 ppm are insufficient. You are making a guess. Still my favorite test strip because I regularly get HOCl readings in excess of 250 and the comparable product only goes to 200. Would love more increments.

I use these to test my hypochlorous acid to make sure it is still effective. These are reliable and easy to use.

These test strips are very good and high quality. The range is very good for weaker and stronger solutions when needed. The color chart and ranges are very easy to read and and easy to differentiate.

I was using needs to make my own age to HOCL and there are very necessary part of making this and they are accurate and easy to use
