HygroSet Super Accurate Digital Hygrometer

Most people don't know, but every hygrometer should be calibrated, how else do you know if it is accurate? Up until now, after you calibrated your hygrometer you had to remember how "off" the reading was from actual humidity. In 2005 I came up with a simple idea. Create a digital hygrometer that can not only be calibrated, but can easily be adjusted after calibration. Simply perform the 75% salt test using our One-Step Calibration Kit or the salt in a bag test, adjust to the correct humidity, press the set button, and your HygroSet is calibrated and ready to go!

Never wonder again if your digital hygrometer is accurate! The HygroSet is the first digital hygrometer capable of being adjusted after calibration. Each click of the adjustment knob changes the humidity display (+ / -) by 1%.

This digital hygrometer was spot on out of the box. I calibrated it to be sure and it was perfect. All this time my humidor was running high. I am using this as a back up to my Cigar Oasis humidifier. As a result, I had to recalibrate the Cigar Oasis unit and now I have perfect cigars at 70.0

This is a good hygrometer at the price, but make sure you follow the calibration instructions that come with it or else your readings will be off.
