Monitor Temperature and Humidity INSIDE Your Safe

GoldenRod GoldenRod Moisture hygrometer wireless sensor

Golden rod hygrometer wireless sensorHere’s a smart new product that monitors the temperature and humidity inside your gun safe — with a convenient LCD display unit located on the outside of the safe. You don’t need to string wires or cut a small hole in your safe — there are two separate components, one inside and one outside. The sensor unit (on the inside) communicates wirelessly with the display unit (on the outside).

The new GoldenRod Wireless Hygrometer was designed to display the temp/humidity in your safe without the need to open the safe. NOTE: the wireless LCD display can show BOTH in-vault AND in-room humidity and temperature levels. You can attach the display to the vault door with its built-in magnet, or simply place the display unit on top of the safe using the handy flip-out kickstand. The unit costs just $26.98 at

Another Important Accessory — GoldenRod for Inside the Safe
The GoldenRod, marketed as a dehumidifier, is a small, low-wattage electric heating element you place in the safe. Running 24/7 at 140° F, the GoldenRod warms the air in your safe. This changes relative humidity and raises the dew point in the safe so water vapor does not condense on your arms and valuable accessories. When combined with Desiccant packs that absorb moisture, the GoldenRod is extremely effective at keeping your guns rust-free during long-term storage. We do recommend wiping down your guns with Boeshield, Eezox, or Corrosion-X before putting them in storage. These are three of the best corrosion-inhibiting metal coatings you can buy.
