The Accurite hygrometer I also use and love it's cheap and very true. Plus Home Depot sells them and you can easily return if it's off too much Rh. I actually know somebody who retuned 3 till he got one that was perfect!

Question? Are you using a fresh boveda for calibration? I've never had success with the calibration packs. Always grab a fresh boveda close to my preferred Rh and throw in bag with hygro. Has worked every time

I was going to take one of the new 320gram 65% packs I have and do it that way. I read a few places that calibrating them at lower than 75% will give inaccurate readings, which didn't make sense, since we are monitoring them in that range anyhow.

Maybe I will give that a try before buying different units. I will take 2 of them and put them in a thick ziplock freezer bag and wait 24-36 and see what they read.

Still wouldn't mind some input on quality hygrometers that you guys trust, in the event I can't get these to work right.

Thanks for the help
