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,
