Type Chlorine Test Strips


Noble Chemical CM-240 chlorine test paper is the simple, reliable, and economical way to measure the concentration of free available chlorine in sanitizing solutions. This test paper measures concentrations between 10-200ppm (parts per million), with color matches at 10, 50, 100 and 200ppm. The distinct color match at each full unit makes it easy for the user to identify the correct chlorine level. Simply tear off a small strip of test paper, dip into the sanitizing solution, blot with paper towel, then instantly compare the resulting color with the matching chlorine color chart. The paper is held in a convenient, plastic dispensing container. This test's distinct color chart and accurate, reproducible readings give an immediate response for quick and easy use.

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. Sanitizer solutions are essential in the food service industry to ensure that sanitizers are at the proper concentration specified by the individual manufacturer.

Includes (2) 15' rolls of test paper and matching color chart. Provides for approximately 200 tests per roll. These test strips should not be stored in an area with high humidity or in an area where they may be exposed to water before use.

    from McFen Custard LLC Posted on

    The test strips are awsome at testing clorine levels and the size of the strips are so small that it takes no space at all to store.

    from Natures Smoothies Posted on

    Small size takes up very little amount of room in our storage room and the container is air right - dropped in the sink while trying to test our sanitizer and the ribbon inside was still dry!

    Small, compact, and easy to use. Simple to understand instructions on the container. Easy to read and something that the health inspector always likes to see.

    Bought these because I need them to fulfill the State's requirement. Webstaurant.com had the best price and I like them so far. They test the chlorine in the water for dish washing.

    from The Tea Room Posted on

    These are very handy. Our health inspector likes us using these and that makes everyone happy. It is a small package when storing and seems to get mixed up in stuff making it a little hard to locate sometimes but they woke well.

    from Red River Inn Posted on

    These work perfectly for testing sanitizing water. The roll should last for a while and it always keep the health department inspector happy to see them.

    Health code requires these in our state so it's nice to get them at a decent price. They work well. We will certainly buy again.

    from Highland Table Posted on

    This test paper is perfect. It is small and fits a fair bit of test paper. An essential tool according to my local health department.

    These work as they should. The dispenser is a definite plus -- no more trying to fish out tiny test paper strips from a container. Great price too.

    from Green Cup Cafe Posted on

    Works great to pick up chlorine but dont fare so well from tearing. If you are new to test strips, be sure to check with local agencies as to exactly which ones your particular facility is required to have on hand.

    from Sugarbelles Posted on

    I couldn't believe the pricing on this product! Amazing and what's more is that it comes with an extra roll of test paper! I love Webstaurantstore's savings!

    from Roll'n Pin Posted on

    from Zeppe's Pizzeria Posted on

    We really enjoyed these test strips. They're very easy to use. They sure do come in handy. We will definitely order more when we need them.

    from Cupcake Cafe Posted on

    These Noble Chemical chlorine test strips do what they are suppose to do which is give an accurate reading. We will probably start using them at home so as to cut down on our chlorine usage.

    This product is great, paper tears easily with no struggle. Perfect size to not get lost but not be in the way either. Color chart is easy to read as well

    from Coalesce, LLC Posted on

    Works great you need to keep a set on hand to check chlorine these chlorine test strips don't rip easy like others I have got will be buying again

    from Kendra Locke Concessions Posted on

    Very effective when trying to determine your chemical strength. I use it once and a while. But it is a must have by any health department.

    from Pretty Odd Wieners Posted on

    These are very handy to have and I really like the dispenser that it comes in, though it is quite tiny. It is easy to rip off the amount of strips that you need.

    from Honeybee Patisserie Posted on

    This is a good price for chlorine test strips. They are handy in the kitchen and I even need to carry them to farmers markets.

    from Frau Pretzel Posted on

    Fast reacting chlorine test trips. We love the clear, tear off case. This is one lo9ng roll of test strip that you can tear off as long as you like. Much more efficient than the pre cut type.

    from Gilpin Market Posted on

    We purchased these strips to check the chlorine and they work really well, you can tear off as much as you need and this saves from waste.

    from Green Zone B & G Posted on

    Hard to write a review about, but these do the job well. They work well and dispenser keeps the strips in place. I will buy more.

    from Goodness Bake Shoppe Posted on

    Nice product to have in the kitchen and like they are in a dispenser. We leave them above our three bin sink to leave the test strips in for easy access.
