Hmm, the pipette is interesting but the accuracy isn't very good. +/- 25 ppm (6%) at 420 ppm? That means your reading could be anywhere from 395 to 445 if your water was really at 420. This accuracy doesn't instill much confidence.

Good point... never really looked at the accuracy information for any test kit...

wonder if Red Sea and Salifert disclose their accuracy information.... gonna go check now...
