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

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.

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

Good

does the job

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

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.

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

Perfect little pack. Nothing fancy, but compliant for manufacturing.

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

Excellent, exactly as ordered, arrived quick!
