Your firearms are an investment worth protecting, and that starts with controlling the environment where they're stored. The Lockdown 222111 Vault Hygrometer with Fastener/Hook is a precision humidity gauge designed to monitor moisture levels inside gun safes, vaults, and secure storage spaces. Rust and corrosion don't happen overnight—they creep in quietly through excess humidity. By keeping tabs on relative humidity with a dedicated vault hygrometer, you catch problems before they damage bluing, finishes, and internal mechanisms.
This hygrometer gives you at-a-glance readings with large, easy-to-read numbers so you don't have to squint or guess. The fastener and hook hardware make installation straightforward in any vault or storage cabinet. Whether you're storing rifles, pistols, or a mixed collection, maintaining humidity below 50% is one of the simplest and most effective steps you can take. Pair it with a quality dehumidifier or desiccant pack, and you've got a solid defense against the silent enemy of metal and wood.
Built for the realities of gun storage—no nonsense, just accurate information to keep your collection dry and protected.

Frequently Asked Questions
Why do I need a hygrometer in my gun safe?
Excess moisture inside a safe or vault accelerates rust and corrosion on firearms, especially on blued and stainless steel surfaces. A hygrometer lets you monitor humidity levels so you can take corrective action—like adding a dehumidifier or desiccant—before your guns are damaged.
What humidity level should I maintain?
The industry standard is to keep relative humidity below 50% in any enclosed firearm storage space. This hygrometer helps you track whether you're in that safe zone.
How is this hygrometer mounted?
The Lockdown 222111 comes with a fastener and hook hardware for mounting inside your safe or vault. Installation is simple and requires no tools.
