Been using my glass hydrometer with great success for a couple of years when I finally got a Tilt, which I love...
...But...
It reads about .005 off from my glass one.
"A man with two hydrometers is never quite sure of his gravity."
So, the Tilt can be calibrated, in much the same way that many thermometers can, but I never really trusted "make sure it reads correctly at 0° and 100°C, then it will probably be close enough at 50°" thing. I guess I've just seen too many performance curves to trust that.
...But here I was, trusting my glass hydrometer right out of the box without even calibrating for all this time.
Anyway... I do actually have a question.
Is there some sort of "reference liquid" or something that one can use to calibrate closer to 1.060? If I tested at 1.060 and got a good reading (or calibrated to it), it would be a lot easier to trust 050 & 070. But getting a good reading (or "off by" value) at 1.000 just doesn't instill that same level of confidence.
How to reconcile?
Thanks!
