The test cylinder that came with the HTH 6 way I started out with is graduated with 5, 10, 11, 14.5, and more, up to 50 ml.
Could I use the 5 ml for FC/CC testing, and count the drops of R-0871 as full ppm? what would this do with the CC portion of the test? 2 or 3 drops of R-0003? Just curious.
Not really worried about the reagent usage at the 10 ml testing, reagents are cheap enough when compared to being "pool stored".
