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

good

Perfect for my food truck. Everything I expected.

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.

:)

I didnt like the container I would like something that I can hang on the wall or a base so I can please on a flat surface straight up so we can see it

I was looking for a wider range but the quality is good.

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

It was very good.

Works

Not much to say but other then it’s the real deal. Not a fake knockoff, will buy again.
