### ⭐⭐⭐⭐⭐ Pro quality hygrometer
*by K***H on October 20, 2025*

Took a chance on this not well-known brand. I've been using this in my HVAC career. It is accurate and very easy to use. I can honestly say it's the best hygrometer I've tried yet. It has regular dry bulb and relative humidity readings.. It also has dew point and wet bulb temperature readings. And many other features also. For the he price, this one is a winner
