Boveda Hygrometer Calibration Kit - 32%

Boveda's patented "One-Step Hygrometer Calibration Kit" is used to check the accuracy of your hygrometer. The One-Step Calibration Kit produces an internal environment of 32% humidity. To calibrate, place your digital hygrometer into the zip-lock bag (included).

If your digital hygrometer is adjustable, then follow the manufacturers instructions to calibrate it to 32%. Otherwise, you can make a note of the difference your hygrometer reads and 32% to establish an offset.

Hygrometer not included and the small brown bag does not need to be opened.
