AquaChek Select Test Strips - Includes Color Chart & Comparator

AquaChek's Select test strips allow pool and spa owners to test their systems for free chlorine, total chlorine, total bromine, pH, total alkalinity, and cyanuric acid. Simply insert the test strip into the pool or spa water for 1 second, and several seconds later you have fast, accurate results. It is recommended that you test your spa before each use, and pools a minimum of twice per week, to get an accurate picture of the health of your system.
