Chlorine Dioxide Test Strips

I purchased these strips and some DX50 solution, to treat my water tanks. I thought the strips would let me know what dosage strength I had in the water. I have learned since that they do not measure anywhere near the dilution that is used for potable water supply, so I can't use them - no colour change at all on the pad. I feel selling them alongside the solution is a bit misleading. There is a note now saying they won't measure the low dilution for potable water, but there is also a note saying 'it is a convenient way to test for sanitised water' ?
