SWMBO ordered me the standard brewer's model w/ ATC from Brew Hardware.
As I was reading the instructions last night, I have questions about calibration and use of this instrument.
Calibration must be done with 68 degree distilled water ( I get that)
But the directions also mention that the refractometer should be calibrated at the temperature that it will be used.
I brew outside (in Northern Vermont) and this weekend when I brew my first AG the temperature is supposed to be in the 40's or 50's (we are currently having a not normal stretch)
So I need to calibrate this thing outside?
If so, i am positive that the distilled water for calibration will not be 68 degrees.
The directions also mention that sample and air temperature should be the same.
I thought the whole point of a refractometer with ATC was to be able to check gravity of runnings on the fly as I am doing it.
HELP me understand all of this....
