Never wonder if your digital hygrometer is accurate!

The HygroSet® II is the first digital hygrometer of its kind 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!
