"Insoluble colorimetric indicators are impregnated in the membrane / filter paper and positioned over the aperture. When a SenSafe™ strip is dipped into the water sample with back and forth motion, fluid flow is facilitated through the aperture which improves colorimetric reaction with the indicator up to 100-fold, when compared to other conventional test strips." -- source
Quite literally, the term 'SenSafe' refers to the combination of sensitive testing methods with the safety of test strips.
( Sensitivity ) + ( Safety ) = SenSafe
No other test strip in the World besides the SenSafe Free Chlorine Water Check has obtained the EPA's Approval for use in drinking water! -- source
Detection Range for SenSafe Free Chlorine Water Check: 0, 0.05, 0.1, 0.2, 0.4, 0.6, 0.8, 1.2, 1.5, 2, 2.6, 4, 6 ppm (mg/L)
Other SenSafe Products Include

"WaterWorks™ strips are designed using a combination of patented and proprietary
chemistries. All needed reagents are precisely impregnated on the test pad. In
comparison to standard powdered reagents, WaterWorks™ strips use approximately
1/100th the amount of chemicals. Designed to yield semi-quantitative and
quantitative results, WaterWorks™ strips are ideal for use for many
water testing needs." -- source
"Designed using cutting-edge chemistry, our kits report results in as few as 12 minutes
and detect from 0.3 ppb. Our patented test kits are used worldwide and recommended by
numerous states. Performance and accuracy of these kits have been verifed by the USEPA
through the ETV program
( www.epa.gov/etv). These
easy-to-use kits require no technical training and are recognized throughout the world as
premium inorganic Arsenic field test kits." -- source
