HygroSet Super Accurate Round 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 is the second one I've purchased. The 1st one is still going strong and this one is for a new humidor.

Excellent product - excellent service

The hygrometer is exactly as expected. No frills or fancy bells and whistles, this hygrometer was easy to calibrate (salt method) and works like a charm.

Accurate hygros

Great vendor – excellent product

I’ve been using the same hygrometers for years and they work really well. I would highly recommend them.

Great hygrometer

I bough a total of four of these little hygrometers for two new humidors and two existing humidors. I wanted to be able to compare them altogether in one space and then be confident in the readings in the individual humidors. They are great to use and very accurate.
