A gun safe hygrometer is a device which can be installed in a firearm storage safe to measure and report internal levels of humidity at any point in time.
Excessive humidity remains one of the biggest threats to the safe storage of guns and other personal effects.
Therefore, you can’t afford to take your eyes off the ball when it comes to monitoring atmospheric vapor levels in your safe.
Variations in temperature can lead to a buildup of moisture which eventually settles on guns, ammo, and other personal effects such as jewelry.
This inevitably leads to rust, corrosion, mildew, and other unfavorable conditions which can cause irreparable damage to your valuables.
It’s no secret that metals such as steel and aluminum have been the most dominant raw material in the manufacture of handguns, assault rifles, shot guns, and other types of firearms for many centuries.
When these metallic components are allowed to come into contact with oxygen and water, corrosion and rust inevitably kicks in.
If you live in a tropical or sufficiently humid region, investing in the right desiccant to keep your guns dry is imperative.
The stakes become even higher for those with safes containing firearms mounted in their garages or basements.
Garages and basements are usually not climate-controlled and therefore moisture tends to build up quickly in mounted safes. leading to quick physical deterioration of your precious guns and ammo.
OK so you have installed a banging dehumidifier in your gun safe and everything looks good.
But, how do you know your guns are still not being exposed to too much moisture? This is where the need for a digital hygrometer springs up.

Best Hygrometer for Gun Safe Shopping Guide
All hygrometers are not made same. Some models can make your life so much easier compared to others.
So, how do you find the best fit for your gun storage cabinet in order to maintain the physical and mechanical condition of your weapons and other valuables?
Reading Accuracy
The most important factor to consider when looking for any type of hygrometer is reading accuracy. For instance, if the Relative Humidity in your security safe is 75 percent, you wouldn’t want a model that reads 35%.
Wrong readings can give you a false sense of security and peace of mind when you should actually be scratching your head to find a solution.
Going through the customer reviews submitted by current owners on Amazon is a smart way to find out whether a particular model is accurate in terms of readings.
However, the best way to verify accuracy is by calibrating via the salt method.
Calibration every six months or so is actually recommended after you purchase any type of hygrometer. This will guarantee continuous accuracy of its readings.
Ease of Reading
What is the use of having the most accurate hygrometer for your pistol or rifle safe when comprehending its readings is even a problem?
In fact, if you are going to struggle to read your safe’s hygrometer then you may as well not have one at all.
This is because you might never know when the Relative Humidity in your storage safe has reached unhealthy levels. How will you figure out a solution when you aren’t even aware of the problem?
Make sure you get a type with clear-cut usage instructions. The readings should be crystal clear, without any ambiguity.
Also, the numbers should be large enough for you to see it from afar even if your eyesight isn’t the best.
Getting a back-lit model can actually be a good idea if the safe is anchored in an area with less than perfect lighting.
Size
Well, the size of your hygrometer should also be taken into account when shopping. You wouldn’t want a bulky model which will end up competing for space with your guns in the safe.
We recommend that you choose a portable type that can be easily mounted in your safe with minimal footprints.
Remember, size has got nothing to do with accuracy. So don’t be fooled into thinking you need the largest version in order to keep tabs on the safe’s atmospheric conditions
Mounting
If you’re shopping for a gun safe digital hygrometer, you should think about where and how to mount it.
Failure to mount any model properly can jeopardize the accuracy of your results. If a particular hygrometer seems like it’d be a struggle to mount, you should probably move on.
The good news is that manufacturers are putting in a lot of effort to make mounting a breeze. Some brands actually design their hygrometers with fasteners which makes them easy to fix anywhere in your safe.
