We need something fast and accurate for testing different solutions at work. We’ve purchased these before and they worked well for all. Would recommend it to others!

It is important to follow the temperature compensation chart to ensure accurate results. At first I did not follow this(out of pure laziness), and my results were not accurate. Once I conducted the test accurately, it worked perfectly for me. The test is easy and affordable.

I use these strips at my place of employment to test water/solutions. We have had accurate results so far. We have been pleased with this purchase and will continue to buy!

Well, I have to be on a very low Iodine diet for awhile for medical reasons. I bought these strips as a way to differentiate food by Iodine content more granularly than just "low Iodine diets" recommend. Such as, does Himalayin sea salt have less iodine that morton's no added Iodine plain table salt. Double check ingredients i'll be using, my filtered water vs distilled, etc., just to be extra careful. I was excited about these as the sensitivity down to 0.02ppm was compelling.Unfortunately, these strips always result in the same answer, even for things that have significant Iodine in them. Test strips pic attached... I went as far as to go buy iodized salt, known to have Iodine of ~45ug per gram, and made a solution that should be ~48ppm, along with many in between, and always got pure yellow - no Iodine! Since I start my diet in a day, I guess I have to rely on info online for the diet and drink distilled water too. What a waste of time and effort.Note, I'm a ChemE, so i do well know how to do unit conversions and am not making simple math mistakes. if you can't dissolve 2 TBS of iodized salt into 1/4 cup of water and get it to register on these, the issue is the strips are useless. They expire in 11'22, a year and a half from now, so that isn't the issue.

These are NOT for human testing. It should be specified.
