How to know if your analog hygrometer is really working

You’ve just bought a new humidor and it came with an analog hygrometer. You’ve prepped the box, put in the cigars and a week or two later, the cigars feel fine, but the hygrometer is “stuck” at a reading that’s well off the norm by over 10%. This observation is usually followed by anything from “Hmmm…” to panic and fear. No to worry. The important thing is the cigars feel supple and not overly moist or dry.

Remove the hygrometer. Provided it has a calibration screw, using a small screw driver, set the needle to 100%. Put it back in place in the humidor. A spring inside the hygrometer loosens or tightens depending on amount of RH. This is why you want to crank it up to its tightest setting. If the hygrometer is working, the needle will move back down and stop when it has reached its max RH level. This figure may be within range or not. But at least you’ll know it can be calibrated if necessary.
