Hydrion QT-40 Quaternary Sanitizer Test Tape 15 feet Roll Quat Color Chart 0-500 ppm Range

My only complaint is the container is open and is around water so it’s only a matter of time before an employee puts it down to close to water. Every single roll of these I ever bought ends up soaked and ruined with in a week of buying them. And yes I have a place for it and told all the staff not to leave it near water but it always does. Very frustrating design.

Works

It was exactly what I needed may need to reorder again sometime. I definitely will use Amazon. Thank you

Great product. It was very easy to use and understand. Helped us stay accurate with our readings and passed inspection.

Perfect for my food truck. Everything I expected.

Good stuff

Excellent, exactly as ordered, arrived quick!

This measures the concentration of hypochlorite acid and works well. Only weird thing is it goes by 100s except the first one which is 150 ppm. Seems like it should be 100, but maybe 150 ppm is a level that is required more often. Anyway, works well.

Very easy to use, and I love that the strips are tear away so I can make sure Im not wasting any of the strip. You can cut off a tiny piece of it to test the sanitizing solution and not waste several inches of the roll. These strips read out the same as the previous ones Ive used, so they are accurate. Great product.

Fast shipping, easy to use, good product. Would buy again
