The Boveda Hygrometer calibration kit is a simple and meticulous way to calibrate any digital or analog hygrometer.

The setup is simple, open the calibration bag and pop your choice of hygrometer inside and close the bag. Allow 24 hours before opening the bag or amending the hygrometer.

Upon opening, if your hygrometer is accurate it should read 75% the same as the pack if you find that this is either above or below simply adjust it to read 75% and the calibration is complete.

The pack lasts up to 3 months, however, we recommend re-calibrating every 6 months for the best results.

Boveda doesn't require any activation, maintenance, mess-making, or worry.

Claire ★★★★★

Tossed my hygrometer in the sealed bag, waited the full 24 hours, and the reading settled dead-on 75% — took all the guesswork out of seasoning my humidor. The one-step design really is foolproof, and now I trust every reading I get from my other units too.

Joshua ★★★★★

Finally, a way to calibrate that doesn't feel like guesswork—the sealed bag and simple instructions made the process foolproof. My hygrometer was reading 4% off before, and now it's spot on after just a few hours.

Leo ★★★★★

I was tired of guessing if my humidor readings were accurate, and this kit fixed that in about an hour. The sealed bag kept conditions stable, and my hygrometer is spot-on now.
