Is there any equipment out there like the Hanna Checkers but for other tests. Specifically Ammonia and Nitrates.
My problem is that I have problems with some colors (vision), and determining where I am on the color scale gives me problems sometimes. I usually have to wait for my wife to be around to have her look at the colors.
I want the tests to be accurate also (well as accurate as they can be)
