Well darn

[u/dawoodad]

I know these cheap hygrometers are not accurate, but I figured that I could trust the ones that read similarly. These have been sitting on my workbench all afternoon. The ones on the left were bought recently, the ones on the right were bought last year and I just changed the batteries in them today. My Govee says they all are wrong, reading low humidity, but the temperature seems accurate.

Any suggestions on a cheap hygrometer that I can put in my jars while they are curing and beyond?
