Test strips for pools, spas

Industrial Test Systems Inc., of Rock Hill, S.C., has introduced MPS Spa Check, specifically designed for swimming pool and spa owners who currently use an alternative sanitizing system that utilizes monopersulfate and a sanitizing agent. It tests for monopersulfate, pH and total alkalinity, and gives accurate results in less than 30 seconds. MPS Spa Check with technological advances improves the often-difficult task of color matching.
