Quaternary Ammonium Test Paper Strips, 0-500 ppm, 100-Pack | Sanitizer, QAC, Multi Quat, Made in USA, for Restaurant and Food Service

5 stars for the container alone. I can keep it in the sink drawer and not worry about it getting wet like the rolls with containers that fall apart. Very fast results too.

Worked great for my food truck sanitizer water to make sure we have the right amount in. Will also need to have on site per food inspector.

Works as it should

There's no way to verify the strips accuracy but it is what it is.

Retired Food Safety person in fresh produce processing. Quat is part of normal sanitation, but “leftovers” aren’t kept for the next day. At home during a quarantine it’s nice to be able to test the spray bottles for strength daily rather than remixing. At home I’m using Steramine tablets in 1/2 gallon H2O for a 400 PPM solution.

I own a Restaurant and saw these on Amazon looking for other Supplies and thought I would give them a try. Glad I did. You can cut them in half and get double your money. They seem to test more accurate than other strips I've tried. I will continue to buy.

This is doing the trick for now. I have to record ppms at work for sanitizing. The stripes are tiny and come in a little storage container. The coloring is a little off once it has tested solution. I questioned myself of being color-blind. For now usuable.

I like the instant water solution content scale to target knowing safe sanitation at it's best. Great product idea, will buy more for our test kitchen.

Good product, good pruce

The delivery came right on time and date promised. Goods were satisfactory.

I sent my staff out to search locally for these, but they came back with chlorine test strips instead. I guess the guy they spoke with was confident that was what we needed. This is actually what I needed as we use the pink stuff to sanitize our dishes and spaces.

Worked as expected

sent me expired product and health inspector nailed us with a citation 3 months expired before the actual order date
