Just got these out of the package and they have been sitting right next to each other for over 15mins. No way to calibrate these. Wouldn't recommend them.

Bought these hoping one of them would be somewhat accurate for my travel humidor. Put them in my desk top humidor and they were both spot on with my other hydrometer within minutes. They're obviously made cheap, but I mean, for a few dollars, you can't expect much. Fits perfectly in the lid after a quick drill and glue and I don't have to open my humidor just to check the humidity. I don't imagine these will last long with very much abuse, but for what I need, these are perfect.
