Humidipak's Patented One-Step Hygrometer Calibration Kit is used to check the accuracy of your hygrometer.
Description
The One-Step Calibration Kit produces an environment of 75% humidity. To calibrate, place your HygroSet Digital Hygrometer into the ziplock bag (included).
If adjustment is necessary, your Hygro-Set features an adjustment knob to zero in on the correct humidity reading. The Hygro-Sets are the first digital hygrometers in the cigar industry to have this feature.
