I bought a Blau U-shaped drop checker because I was interested by the shape- it looks really sleek. However, I put 4 dkh solution in it and installed it right next to a more traditional drop checker for comparison's sake, and now (five hours later) they do not agree.
Is the Blau a bust, or is it not a fair test because I didn't put fresh solution in the traditional drop checker today?
(Please excuse the dirty inner glass, am waiting on a delivery of snails and want them to have something to eat when they arrive.)
