Why are test strips manufactured by ITS superior? Our test strips combine sensitivity and safety. That’s how SenSafe™ test strips got their name. What makes them unique is the patented aperture (window) technology. This unique design allows for the lowest sensitivity possible on a test strip. SenSafe™ test strips, when dipped in a water sample with a back and forth motion, allow the aqueous solution to pass through the thin membrane as shown in the graphic. Coupled with this design is another unique feature: the SenSafe™ test strips contain only 1/100th the amount of chemical compared to most common 10mL test strips. We strive to make our tests environmentally-friendly and accurate while making complex chemistry simple.

Insoluble colorimetric indicators are impregnated in the membrane / filter paper and positioned over the aperture. When a SenSafe test 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. Only ITS offers this patented and unique strip.

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.


Now there is an alternative to powder pillows, powder packets, tablets, glass ampoules, and liquid systems: eXact® Reagent Strips! Each strip has one or more test pads containing reagents for colorimetric detection of ions in water samples. By dipping a strip into a cell, the exact amount of reagent is released into the water causing a reaction. The reaction inside the water sample is measured by light inside the photometer giving the user fast and exact results.


ITS features an impressive array of inorganic Arsenic Quick™ test kits that provide accurate results at affordable prices. Designed using cutting-edge chemistry, our kits report results in as few as 14 minutes and detect from 0.3 ppb. Our patented test kits are recommended by numerous states. Performance and accuracy have been verified by the USEPA through the ETV program (

What are Foil Packets?

Packets are a convenient way to package individual test strips. Providing total protection for the strip, foil packets are an ideal solution when you are working in varying conditions where the risk of exposure to extremely high humidity and moisture is possible. Each strip is carefully sealed in its own individual packet to protect it from exposure to moisture before you are ready to use it. Another benefit to foil packets is the size. Small enough to fit in your pocket, foil packets are an ideal solution when testing out in the field. Considering the size and protection of a foil packet, they are ideal to send to customers as a promotion or troubleshooting tool; saving time and money compared to a service call.
