Hornady Digital Hygrometer Red AAA

The Hornady Digital Hygrometer is a compact indoor climate monitor designed to track conditions inside a gun safe, vault, or other enclosed storage space. Finished in Red, the unit pairs a clean housing with a large touchscreen display that delivers at-a-glance temperature and humidity readouts.

Beyond the live temperature and relative humidity, the hygrometer logs the high and low values for each so you can spot moisture and temperature swings before they damage firearms, ammunition, optics, or other valuables. Readouts can be switched between Fahrenheit and Celsius directly on the touchscreen. The unit operates across a temperature range of 14 to 122 degrees F (-10 to 50 degrees C) and a humidity range of 10 to 90 percent relative humidity.

A quick-connect mounting bracket installs on the interior of the safe door, letting you remove and reinstall the display without tools. The hygrometer measures approximately 5-1/8" tall x 3-1/4" wide x 1" deep and weighs just 1.68 oz. Power is supplied by two AAA batteries, which are not included.
