Madelaine Analog Hygrometer
From Madelaine, makers of some of the world's finest cigar accessories, comes this very affordable analog hygrometer. It features an easy-to-see red needle with the preferred relative humidity (RH) zone highlighted in blue. Suggestion: Add a Boveda Calibration pack to check it for accuracy.
Opened the box and was on zero. Stayed there all day. Tap the side and the needle just bounces around.
Does actually work. Boveda tested it and it s dead on. Also dead on with other calibrated hygros, with no adjusting necessary. Really does work out of the box.
I just bought a couple of these as kind of a back up to my digital ones. I'm amazed that they were actually accurate right out of the box. I put them in a bag with one of my trusted digital units and gave them the old salt test. They were spot on 75% RH just like the digital. I didn't have to adjust them at all.
