Product Features

Ensure your solutions are safe for use with these Noble CM-240 chlorine test strips!
Noble CM-240 chlorine test strips are the simple, reliable, and economical way to measure the concentration of free available chlorine in sanitizing solutions. Each strip measures concentrations between 10-200 ppm (parts per million), with color matches at 10, 50, 100 and 200 ppm.

Easy-to-Read Color Chart
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.

Accurate
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.

I prefer these to the roll. The rolls tend to unravel and make a mess/waste.

Nice and easy. Big savings. I purchased these because it is a mandatory requirement from my local health department as I run a vacation rental. I have not personally used them, however they are available in my rental for guests and I have had no complaints. Definitely worth the price.
