Very High Level Quaternary Ammonium (QAC, Multi Quat) Sanitizer Test Strips, 0-10,000 ppm [Vial of 50 Strips]

These strips are good for higher concentrations, other test strips are available to measure lower levels. The range is wide but the results are read immediately which helps provide the resulting accuracy. They are plastic strips with the test pad on the end, very easy to use. Have used them with concentrated solutions to find ppm and they have indicated 5000 ppm which is what was expected.

Accurate so far as I can tell. Isn't the point of the strips that you can't tell otherwise? Anyways, more diluted solutions do not register so I assume these are in fact accurate.

Need this to control concentration of sanitizing chemical we use. It works well. Easy to read. Very quick results.

Very accurate and easy to use

Excelente!!
