Review on Enhanced Accuracy Alarm-Enabled AcuRite 01080M Temperature and Humidity Gauge in Black by Nicholas Harrington

Adjustable - Forget everything else for a cigar hygrometer. I returned the last 4 I bought because they were inaccurate and couldn't be adjusted enough to fit them (they were over +-6). I did a salt test and adjusted accordingly. It quickly changes/adapts to changes in humidity. The temperature was correct, but you can also adjust it. The alarm works great. Set high and low beep levels. Too bad I had to buy 5 others which I returned before trying this one. Hope that helps!
