NOTE: Because most of our products are test strips or use reagents that have little or no hazard in the quantity sold, MSDS sheets are not
supplied with the test.
To ensure optimal performance, store your eXact
®
kit in a cool, dry place away from excess heat (below
90°F / 32°C), moisture, and oxidizers such as Chlorine and Bromine.

This DPD test system is accepted by most state health departments because this test is USEPA (DIN
Standard 38 408 G4, ISO 7393/2) accepted for testing requirements for Free and Total Chlorine. The
H;DFW
®
Eco-Check meter uses a wavelength of 525nm; and the compliance requirement is that the
