Mini hygrometer

[DakiniKush]

I usually go by feel but feel after all this time to stop being cheap. So I got 5 mini hygrometer to put into my jars after drying. Well I'm still drying but when it's time to use them do I calibrate somehow or from package into jar?

no calibration on the cheapie plastic ones, they can go straight to jar, but I would set them all on table beside your regular hygrometer and let them air for an hour to see the readings are the same.

The best way to know if your hygrometers are calibrated properly is to do the salt test.
Put your hygrometers in a freezer bag along with a water bottle cap filled with wet salt........the wet salt is exactly 75% humidity. Leave it for 24 hours and you'll know how to adjust.......if your meter says 73% it means you have to add 2% to whatever the reading is.

Some are able to be calibrated others are set and no way to adjust them if need be. I store mine in a jar when not in use with one of the Bovida 62 packs, then I can tell if they fairly close when I want to use them again when going into jars to cure to make sure humidity is low enough.
