Hygrometer calibration
« on: February 06, 2018, 08:45:55 PM »
I recently bought a very old Airguide brand thermometer/hygrometer. Does anyone know a way to calibrate an older style hygrometer that uses the paper-metal coil? They aren't overly accurate to begin with but if I can adjust it a bit, I think it'll be close.

Thanks!
