> 24 hourGood option for restaurants. We used in our business and worked well to test sanitizer. Easy to use and tear off only what is needed.

> 24 hourI use this product all of the time to ensure the proper ppm for quaternary ammonium sanitizing solutions. Colormetric paper is easy to use and colors match the reference chart appropriately.

QT54
> 24 hourThis 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.
