Prestige Import GroupMedium Round Analog Hygrometer Humidity Gauge for Humidors - Color: Gold

Small compact design. Humidity reading was close enough so I didn't have to adjust it.5/12/25 : Bought a second one to set up a 2nd Tuppadore. Calibrated using a Boveda packet and all is well. Calibration involves disassembly and moving the mechanism to the proper reading. Google it to find how to disassemble. (note: there appears to be a little screw on the back for adjustements. IT'S NOT A SCREW. So don't try to adjust it with what looks like a screw)

Lost a bunch of cigars because of this hygrometer. I calibrated it as instructed. Placed it in the humidor and kept checking, and the needle kept always saying the same thing, which I found odd, but decided to trust humidity was at good level. I was dumb not to check and refill the water in the humidor. Turns out all my cigars were ruined because the hygrometer needle just wasn't moving, so all my cigars dried out before I noticed the problem.

Looks great , seemed calibrated on arrival, way out of calibration within days after install.

When calibrated with the salt test, it maintains the accuracy. Heavy duty, well made, good looking.

Calibration was simple and working well so far
