Easy-to-Read Color Chart

Each strip measures concentrations between 10-200ppm (parts per million), with color matches at 10, 50, 100 and 200ppm. 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 chlorine-based 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, blot with paper towel, then instantly compare the resulting color with the color chart.


Sanitizer solutions are essential in the food service industry. These strips ensure that those sanitizers are at the proper concentration. For accurate results, 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.

Noble Chemical Test Strips

Whether you need a quaternary or chlorine test to help keep your establishment up to code, these Noble Chemical test strips are sure to help with the job. Check out this video to learn more!

Keep up with health codes with these Noble Chemical test strips. We offer both quaternary and chlorine tests depending on your type of sanitizer. Both are available in rolls, which can be torn to a desired length or in pre-measured strips. Each bottle or dispenser comes with clear, easy-to-follow instructions to ensure accuracy. The quaternary test takes about 10 seconds, and the chlorine test is practically instantaneous. To make things as simple as possible, there's also an included color comparison chart in each kit. Simply compare your results to the chart to ensure proper levels. Dialing in just the right amount of sanitizer is important. You want to be using enough to effectively sanitize, but using too much is just like pouring money down the drain. The quaternary test measures from 0-400 parts per million, while the chlorine test measures 10-200 PPM. By finding the perfect balance, you'll be able to maximize profits while complying with regulations.
