Ugh... that sucks. It's also a mistake I've made. I let my little guy play with the refractometer a few times and forgot to check calibration of it after. It was quite low, reading 1.019 when it should have been 1.026. Luckily everything was okay but I let it go on for far longer than I should have. Hopefully that's the worst mistake I make with this hobby...
