Wouldnt this be fine and dandy to CC some heads.

It might be for the guy installing a cam dot-to-dot. That's for hydroponics and accuracy doesn't need to be spot on. I use a glass burette that is certified for lab use. They cost about $80 without the stand nowadays I think. It's kind of like my $1200 certified sonic tester that "does the same job" as the $300 imports.
