Hydrion Cm-240 Chlorine Dispenser 10-200 PPM Test Roll Plus Extra Roll Plus

Works perfectly fine. Slightly expensive but reliable

Excellent

*Edited to add that EcoLoxTech no longer includes a dispenser of these test strips (or the salt, for that matter) with their EcoOne hypochlorous acid generator. It appears that they do toss in a few sample strips, but not the whole roll.* These chlorine test strips were included with my EcoOne hypochlorous acid generator, though I have purchased more on amazon, since. At first, I thought it was a mistake, because once removed from the dispenser, the roll was wrapped in copper-colored foil, and resembled a chocolate coin. It's also very small (about an inch and a half in diameter) and narrow (I'd guess an 1/8" wide). The tape tears easily with the serrated teeth on the edge of the dispenser, but I prefer to cut it for testing my hypochlorous acid cleansers. It measures the concentration of the levels of free chlorine, from 50-200 parts per million, so those reviewers who are getting blank white test results must have far more chlorine than these strips can measure, or so much chlorine that the strips are being bleached. I will continue to buy and use these strips to confirm that my household cleanser is sanitizing and disinfecting at the levels necessary. If you are interested in the EcoOne, or the Force Of Nature hypochlorous acid generators, they are both available on amazon and have changed the way I clean for the better, forever. If you are on facebook, and are curious about this technology, look for my group for Force Of Nature fanatics, EcoOne enthusiasts, and hypochlorous acid aficionados. Feel free to ask any questions you may have about uses, safety and making your own salt-vinegar-water solution. Yes, it can be done, and done safely, despite what FON would have you believe. Hope to see you around and happy cleaning!

I've been using test strip for years.

Excelente producto

lasts forever, super accurate. i use it to test my hypochlorous acid batches both immediately after brewing, and also throughout the weeks to make sure they maintain their potency.

I'm pretty sure I will never need to be chlorine test strips ever again after this! It comes with a 15 foot roll PLUS another 15 foot refill roll. The chart on the front of the packaging makes it super easy to read your results without having to worry about losing a little paper chart like so many of these kits come with.
