  Opens the Hach Certificate of Analysis Download Tool. A Certificate of Analysis (COA) is a signed document provided for customers who require documentation of reagents they use in testing.

It lists tests performed, the tolerance/outcome allowed for each test, results of the tests on a sample of that lot, and lot expiration date.
