I bought 4 hygrometers for curing- two are the caliber IV type and two are a bit larger black and white temp humidity readers that you see in many forum pics.
I put them all into an airtight container with some boveda 62 packs for a day and the two caliber meters read 62 while the other two read 64 and 65.
I marked their differences from the expected result so that I can adjust their readings when I use them in drying and curing.
The weird thing is that when I put them on the same shelf, next to each other in the room that I am going to use for drying, they no longer read with the same differences.
The calibers read about 1 to 2 points different and the other two can be 4 to 5 points different.
Why would hygrometers that read the same in a sealed container then start to vary when placed in the same room environment right next to each other?
There was no fan going in the room at the time and no open windows.
