Hornady Digital Hygrometer Red AAA 95909

So, you've got a dehumidifier in your gun safe, but how can you know it's keeping humidity levels at the right point to protect against corrosion? You need a Hornady Digital Hygrometer, which measures both temperature and humidity inside a safe or security closet.

Each Hornady Digital Hygrometer is equipped with a large, digital, touchscreen display and can show both thermometer and temperature measurements in Fahrenheit and Celsius. A quick-connect bracket is included with each hygrometer, allowing the unit to mount on a wall to safe shelf space.

Users can also deploy a fold-out stand for use on the floor or an open shelf of their safe, if desired. The Digital Hygrometer is powered by two AA batteries.
