With 3 tests combined into one strip, testing is super easy and efficient. No confusing testing with the new Pool Check COPPER 3 in 1. Just dip and read results in seconds. Test for Total Alkalinity, Copper, and pH all at the same time.Using our patented aperture design, Copper test strips allow the aqueous solution to pass back-and-forth through the impregnated chemical membrane. This unique design allows for the lowest sensitivity possible on a test strip. Coupled with this design is another unique feature, they contain 1/100th the amount of chemical compared to most commonly used test strips. PATENTED aperture (window) technology is more sensitive and more accurate than traditional test strips. More color blocks result in better accuracy. The pH indicator provides easy color matching for (YELLOW/GREEN/BLUE VS ORANGE/RED)improved accuracy and precision. 5 second dip time with motion allows lower detection levels and even color development NO COLOR BLEEDING EASY TO READ COLORS MADE IN THE USA

These test strips are easy to use. We use a pool ionizer in our swimming pool and use these to measure the copper level. Will purchase again.

My photo shows a strip that is old, so don’t judge the colors. But look at the strip size and shape! Most of them were cut normally though, so this is not a deal-breaker. The problem is that this strip told me my pH and alkalinity were low, pH 6 and alkalinity almost 0. Other brands of strips determined, that was a lie! pH is actually closer to 8!!! Plus yesterday I added a full bag of bicarb. Copper seems on track with my ionizer setting, but I definitely won’t trust the pH/alkalinity readings.

I haven't compared the Cu test to other Cu tests, but the pH is consistent when compared to another pH test kit I have only this usually shows a consistent lower pH than the other pH test kit. but both test kits are consistent, only slightly different.

Easy to use but still check with regular test kit every other time
