WaterWorks™ Free Chlorine 0-25ppm (NCW-480023)

It is a simple dip and read test strip with a precise colour chart on the back of the bottle and the results are shown within 30 seconds. This patented, 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, it also resists interference from monochloramines. 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.
