overview

Take the guesswork out of humidity readings.

This maintenance free calibration kit from Boveda is the most efficient and effective way to make sure your hygrometer is spot on. You simply place your hygrometer inside the bag, close the zipper, and let it sit for 24 to 36 hours at room temperature. Your hygrometer should then be showing a reading of 75% humidity. If not, make the adjustments on your hygrometer to read 75% or note the difference and you’re on your way.
