Can I calibrate my hygrometer using any RH Boveda?
Yes, you can use any RH Boveda to calibrate a hygrometer. The Boveda calibration formula comes pretty close to creating an ideal environment. (Within an airtight environment, the recommended calibration formula for Boveda packs is at a +/- 2% calibration.)
Here’s how to calibrate a hygrometer with Boveda:
- Put your hygrometer or humidity sensor in an airtight environment. like a Tupperware® container or Ziploc® bag.
- Tightly close the container or bag.
- Check back in 24 hours.
- If your hygrometer reading doesn’t match the RH printed on the Boveda pack, adjust by the number of points the hygrometer is off, then re-test using the same Boveda.
For added accuracy, use the professional-level One-Step Calibration Kits.
Do not mix Boveda RH levels in the same container when you are calibrating your hygrometer.
