Product Features

Ensure your solutions are safe for use with these Noble QT-10 quaternary test strips!
Noble QT-10 quaternary test strips are the simple, reliable, and economical way to measure the concentration of quaternary sanitizers, including n-alkyldimethylbenzyl and/or n-alkyl dimethyl ethyl benzyl ammonium chloride, and rocall II. Each strip measures concentrations between 0-400ppm (parts per million), with color matches at 0, 100, 200, 300, and 400ppm.

Easy-to-Read Color Chart
Each strip measures concentrations between 0-400ppm (parts per million), with color matches at 0, 100, 200, 300, and 400ppm. The distinct color chart and accurate, reproducible readings give an immediate response for quick and easy use.

Meets Requirements
Federal, state, and local health regulations require users of quaternary ammonium sanitizer solutions to have appropriate test kits available to verify the strength of sanitizer solutions. This kit meets those requirements.

Easy to Use
The distinct color match at each full unit makes it easy for the user to detect exhaustion of solutions that should be replaced. It also helps avoid the use of excessive amounts of sanitizing agents, to avoid wasting product! Simply remove a strip from the vial, dip the strip into the sanitizing solution for 10 seconds, then instantly compare the resulting color with the color chart.

Accurate
Sanitizer solutions are essential in the food service industry. These strips ensure that those sanitizers are at the proper concentration. For accurate results, the test solution should be between 65 and 75 degrees fahrenheit. Do not test foam. Also, store these test strips away from areas with high humidity or where they may be exposed to water before use, as those conditions may compromise results.

They seem to work just fine. The test colors are bright and easy to see and are nearly instant in their assessment of the water that is being tested. I do recommend them to any business looking to keep track of their sanitation water.
