Test your CDS without diluting it.
These high ppm range test strips are a indispensable. I originally had to dilute my CDS by factor 10.,Take notes to math make adjustments. Done with all that now. These strips have a wide enough range to tell me what I need to know in seconds.

These are dangerous as the measurements were LOW by 90%
I liked the idea of using these high range strips as I could skip the dilution step in measuring up to 3000ppm. However, when I tested the strips by measuring a known 3000ppm solution the results showed only 250ppm. That is quite a difference.Imagine if I trusted the readings. I would be using a solution that is 10x stronger than I thought! That could cause serious problems. I was so appalled I returned these the very same day I received them.I suppose I might have gotten a bad batch. But, be aware, you must test these against a known solution as their quality control can't be trusted.

Does not work!
It’s measurement was way off… Strip should have read closer to 500 like the other brand… instead it read closer to 25!!! Same liquid sample!

Wrong
Absolutely inaccurate by far. The high range chlorine dioxide test strips do not match anything on the color range on the canister. Previous purchases of the identical item were perfect. It’s almost like the wrong strips we’re put in this canister. Strange!
