SenSafe Free Chlorine Test Strips

Municipalities now have a rapid (40 seconds), accurate and low–cost option for regulatory compliance monitoring. The patented design of the SenSafe™ Free Chlorine Water Check test strips avoid errors inherent in currently available test methods. All of the reagents needed to perform the test are embedded in a "solid state" in the reaction area of the aperture. The following excerpt is from an EPA letter of evaluation:

"The false positive and false negative rates were below 0–1%. Method precision and accuracy were characterized in multiple drinking water matrices at varying chlorine concentrations. For example, the validation studies showed that free chlorine recovery was approximately 100% and relative standard deviation (RSD) was generally below 20% for analysis of drinking water samples fortified with 0.1ppm of free chlorine or above; the chlorination level required by National Primary Drinking Water Regulations is 0.2ppm. Finally, results did not vary across different lots of test strips."

Sold in bottles of 50 test strips (part# IT481026) or in 30 individually-wrapped packets with a color chart card (part# IT481126), both with a detection range of 0.0, 0.05, 0.1, 0.2, 0.4, 0.6, 0.8, 1.2, 1.5, 2.0, 4.0, 6.0 mg/l.
