Can I calibrate my hygrometer using any RH Boveda?

While our packs are accurate in an airtight environment within +/-1%, our hygrometer calibration formula is even more accurate within +/-.5%. It sounds like we’re showing off, but it’s just the truth.

Oh, and if you want to use another Boveda pack, you could. But we recommend that you select one other than the 49% RH. Reach out to us if you have any questions about this.
