I have a portable ozonator to clean my fruits and veggies from contaminants and pesticides. I use these to ensure it is working properly. Test is simple to use along with the photometer. Strips are good for over 18 months. Great value for 100 strips

PHOTOMETER REQUIRED! Don’t let the bad reviews deter you from a great product, they clearly did not read the description. No color chart matching! Fast shipping.

No idea that their meter was needed to read the results. It should be made much clearer in the product description. Like a WARNING.

Do not order this. It supplies no color chart to match to results on strip. It says to follow instructions. No instructions come with product. Very poor, I will be returning it.

This reagent is top notch with excellent and very accurate results when used how it was meant to be used; with an eXact micro meter! Bad reviews are only from the bozos that didn't bother to read the item description

So there's really no way to tell what the strips mean because theres no key telling what shades of brown mean what. So the only real good they are for is to tell if ozone is present. Save your money, unless you have access to the legend telling what shades mean what.
