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

Good stuff

Oops. Bought this instead of chlorine testing strips for hypochlorous water testing for sanitation. Ill see if this can find a purpose.

Perfect for our food trailer and the health department approves

I got this for my wife to use at work. I guess it works.

These are a must have when using steramine tablets to sanitize stuff that will be used around food

does the job

Dont sell fake one.

Test tapes work very well, We count on them

I got this to test hypochlorite acid solution but once the paper touch the solution become decolonized pale yello not exactly a reading
