What's the best hygrometer out there?

[SmokinSpider]

I just have one of those little round adjustable ones with the red diamond button. I keep telling myself once it dies or gets too far off I will replace it, but after a few years it keeps within spec tested both with the salt and Boveda.

I will replace it with http://www.theweatherstore.com/nicedihy.html
Price isn't bad considering how much time and money I wasted testing cheapies.

I have a number of electronic hygrometers and none are trust worthy. They are consistent showing the wrong rh. The analog type are my choice. Give them all a salt test every few months. Once their set they all (have about 10) seem to stay close +/- 3 to 4 rh.

This is what I use:

I like it because it is wireless so I can monitor my humidors without opening them. Once I calibrated them, they have been spot on.

I've had good luck with the Hygro-set rectangular ones.

I'll echo the Caliber IV recommendations. I own six of them, plus an older Caliber III. None were more than two points off at either 75% or 65% (both tests using Bovedas), and the Caliber IV is adjustble up to six points plus or minus. About $25 most places, but I've seen them for $20 on occasion. They use the common CR2032 button cells (about the size of a quarter), and should last six months to a year or longer; if your reading seems to be off, it's probably a battery near the end of its useful like. (I buy CR2032s in five-packs and keep spares on hand.)
