Detailed Description
Inaccurate humidity readings can jeopardize your cigars and humidor. The Boveda calibration kit is a self-contained, precise, and reliable solution. Just place your hygrometer or sensor inside the zip-closure bag with the 75% RH Boveda pack. After 24 hours, compare the reading: if your hygrometer shows anything other than 75%, simply adjust by the difference. This process takes all ambiguity out of calibration, so you can trust your readings and maintain the optimal humidity for your cigars.
Patented by Boveda, this salt test kit is far more accurate than homemade tests. It’s ideal for recalibrating multiple hygrometers—useful for humidor setups, guitar cases, or anywhere humidity control matters. For best results, recalibrate every 6 months and never mix different Boveda RH packs within the same humidor or use them with other humidity products, to prevent interference. Trusted by serious cigar collectors and reviewers alike, it’s a must-have for any humidor toolkit.

Used for calibration of Pocket sized hygrometer. If maybe they added an extra bag of a larger size, one that is meant to show the maximum capacity, then maybe this would be a perfect item.

Not the most exciting product but a necessary one. Way easier than trying to figure out a salt test for my hygrometers. I use a hygrometer for all my cigars, guitars, and to test levels in my customers houses, so it’s great to be able to grab a few of these a year from Oxford to make sure everything is reading right.

This is perfect for calibrating all my hygrometers. I have 6 overall that I calibrate twice a year to ensure accuracy. This is as simple as it gets. Unseal the package, place your hygrometer in the bag with the 75% humidity boveda, reseal the bag and let sit for 24 hrs. Once you get the reading do your adjustments. Much more accurate than the salt and water test with less mess. This was the best price I’ve found on this item as well!
