The HygroSet FM has the same great adjustment features as the HygroSet I and II but is made specifically for exterior front mount humidors. The HygroSet FM is capable of being adjusted after calibration. Each click of the adjustment knob changes the humidity display (+ / -) by 1%.
We recommend performing the 75% salt test using Humidipak's One-Step Calibration Kit. Adjust to the correct humidity, press the set button, and your HygroSet is calibrated and ready to go!
