HygroSet Front Mount Adjustable Digital Hygrometer Round
Never wonder if your digital hygrometer is accurate!
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!
Dimensions (Outside): 1 7/8"Dia. x 1/2"TH
