WaterWorks™ Free Chlorine High Eco Packs (NCW-481122)

Part No: NCW-481122

This simple colour test strip, from our WaterWorks™ brand, allows for quick and accurate testing of Free Chlorine in water, at a high detection range (0 to 120 ppm).


It is a simple dip and read test strip with a precise colour chart and the results are shown within 30 seconds. This patented, ultra high range test strip can be used to test water across industries and its unique composition means it does not bleach out, even at levels above 2000 ppm. This test is designed to be used in the food processing field, this test can also be used in other fields across the industry where sanitation is necessary.

It's also useful in checking if a DPD-based test (photometer or comparator/tablets) has bleached out and is giving you a false negative. No other reagents or accessories are needed for this test. We use trace amounts of chemicals on our strips which makes them extremely safe and non-hazardous. They are considered as Articles under OSHA and do not require SDS sheets. This is our new recyclable packaging.

Notes: For best results, run test immediately after collecting a fresh water sample. Ideal Free Chlorine levels kill and neutralize all bacteria in the water. Diluted chlorine bleach solutions and water are a common and cost-effective method for sanitizing equipment in food processing operations.

These methods are very effective in killing undesirable microorganisms. Chlorine bleach solutions may also be used for sanitizing raw fruits and vegetables during the washing or peeling process. Processors should be aware that there are regulations concerning the use of this sanitizer. Chlorine bleach that is used for making a sanitizing solution, whether for equipment or raw produce, must be tested to be categorized as a food grade substance.
