Thanks Will - Do the calibration points matter? One thermometer I was looking at has 5 points: 32, 40, 60, 100, 120°F but that is a mercury thermometer which is illegal in my state. Another thermometer is has 6 points: 32, 50, 68, 86, 104, 122°F Will the fact it's not calibrated at 60 matter? Thanks again
Hi Jeff- that doesn't sound right to me, my knowledge is limited so take this with a grain of salt, but I don't think the size of the cylinder should influence the reading of the hydrometer.
