It seems to work. These nitrate reagents that came with the phosphate and nitrate pro kit that I got were outdated within a few months. The nitrate kit from when it was fresh and when it was expired was noticeably different in how it read and the colors it produced.
So, this test kit works pretty well, but when the time comes that it expires, throw out the reagents and get fresh ones or you're wasting your time with the tests, in my experience.
