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

Simple and easy. Keeps the health inspector happy.

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.

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

realize las pruebas en varios amonios y marca color azul a que se debe?? no marca ninguno de los colores verdes

accurate and easy to use

Worked perfectly to pass the healt dept. Inspection for a concession stand.

Perfect for our food trailer and the health department approves

Great to use.

Small easy to put in the necessary area for sani bucket. Lots of tests in a small package. Works great.

A must have for any commercial kitchen.
