Industrial Test Systems, Inc (ITS) is a leading American manufacturer of instruments and chemistries designed to test water quality. ITS developed over 100 tests and proprietary chemistries (many of which have been EPA/ETV performance-verified), including the first and only EPA approved test strip.

Our most exciting addition, the eXact iDip® Smart Photometer System® is the first and only handheld photometer to provide 2–way communication with a Bluetooth® SMART (4.0) ready Apple® or Android® smartphone/tablet (patent 9429553) with the capacity to test over 45 water quality parameters. ITS has the first NSF approved testing products for the commercial pool market. They earned certification to NSF/ANSI 50, the American National Standard for pool water parameters – for its testing products from the global public health organization NSF International. This certification allows ITS to make verified claims about the performance, accuracy and operating range of their water-quality testing devices specifically, the eXact iDip® photometer. It gives the consumers confidence that the test devices work properly with verified results.
