Salifert says 1005, Elos still says 900 tonight.
I was wrong about Salifert resolution at 30, it's 30 units apart on the lookup sheet but going up in 0.02ml increments. So it's really 15.
I also dropped the vial for the Elos test kit and shattered it into about a billion little shards. Yay me. Man those things break super easy.
