About Pool Check® These test strips are an ideal screening method for swimming pool owners, our visual test strips quickly report conditions for many water parameters. These easy-to-read, cost-effective test strips are the sensible alternative to liquid reagent kits.   About ITS Pool Check® is the pool and spa division of Industrial Test Systems, Inc., (ITS). ITS, established in 1989, is a leading manufacturer of instruments and chemistries designed to test water quality parameters. ITS services industries such as municipal water treatment, food beverage, trucking & automotive, pond & aquarium, pool & spa, educational, and medical diagnostics. ITS developed over 70 tests and proprietary chemistries many covered by our U.S. Patents and ETV/USEPA performance verified tests. ITS developed the first and only EPA approved test strip.   How Our Test Strips Work After dipping the test strip into your water sample for the specified period of time (directions may vary from product to product - be sure to read and follow the directions on each product carefully) the pad indicator system will react and begin to turn color. Remove the strip and wait the specified period of time. Match the test pads to the closest set of color blocks on the color chart. That's all. Say goodbye to counting drops, adding tablets, and waiting for questionable results.
