SenSafe® Free Chlorine & pH (NCW-481025)

Part No: NCW-481025

This Chlorine 2-way colour test strip from our SenSafe® brand allows for quick and accurate testing of free chlorine and pH in water.


This unique strip has been designed with two separate test pads; it is a combination of our EPA approved SenSafe® Free Chlorine Water Check with an added pH test pad, do both can be tested simultaneously. It is a simple dip and read test and you will have your result within 10 seconds. These strips can be used across industry from testing for Free Chlorine and pH in drinking water, testing for sanitizer residue in food and beverage processing and other environments.

Our patented aperture strips are unique in the way the water flows through them and detects the Free Chlorine and pH more accurately. The precise colour chart is found on the back of the bottle and no other reagents or accessories are needed for this simple 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.

Notes: This SenSafe® Free Chlorine Water Check test strip is the ONLY EPA APPROVED test strip used for drinking water compliance monitoring [Published in the 2007 Federal Register (vol 72, no 47, Monday, March 12, 2007 p. 11204, ITS method D99-003)]
