Proper musical instrument care is essential to ensuring its longevity. If you own a wooden instrument like a guitar, you must closely monitor the humidity levels in the room or guitar case you’re storing it in.
When the relative humidity (RH) levels drop to less than 40%, the wood used for the instrument would become brittle. As a result, it not only affects the quality of the sound, but it’s at risk of falling apart anytime soon.
Fortunately, a guitar hygrometer makes both temperature and humidity monitoring hassle-free.
If you’re looking for the best hygrometer for guitar in the market, you came to the right place. Here, we’ll introduce you to the best hygrometers and hygrometer-humidifier combos to help you pick the perfect one for you.

Things to Consider When Buying a Hygrometer for Guitar
Now that you know our top picks, we’re sure that you might be torn between two or more of these options. To help you narrow down your choices, here are some of the things to consider when buying a hygrometer for guitar.
Without a doubt, accuracy should be your first consideration when buying the best guitar hygrometer. As much as possible, it should be extra sensitive to the humidity levels surrounding your guitar to deliver accurate readings.
When the readings are not accurate, you run the risk of maintaining humidity inside a guitar case or guitar room that’s beyond the recommended range. As a result, that will cause the guitar’s material to deteriorate faster than it should. That means the purpose of buying the guitar humidity meter will be defeated.
The best hygrometer for musical instruments often features attachment mechanisms. This feature allows it to be mounted on various parts of the instrument to accurately measure relative humidity levels. this is often the case for guitars, where you can mount the hygrometer on the soundhole or the neck.
But in most cases, users are satisfied with placing the device near the guitar. In this case, you won’t need an attachment mechanism, since it can easily fit inside the compartment on your guitar case. The choice depends on which will be the most convenient for you.
It’s also important to consider the readability of the hygrometer, so you can easily tell the status of the air surrounding the guitar.
Fortunately, most modern hygrometers now come with a digital display that allows us to read everything. We don’t have to rely on a shifty dial just to get a good reading on the relative humidity.
If you’re using a digital hygrometer for guitar, it’s best to check its battery life as well.
When a device has a decent battery life, you don’t have to keep recharging or replacing the battery often. That will save you a lot of time and effort – not to mention, you will be able to continuously monitor the air’s humidity. Also, the worst thing that could happen is to have the battery die out when you need it most.
It also helps if the battery is fast charging. This way, your guitar won’t be left unmonitored for long.
Some hygrometers come with a thermometer, while others come with a convenient clock feature. In some cases, you can purchase a hygrometer and humidifier combo, so you can truly maintain the correct humidity level for your guitar.
Of course, these added features also come with an extra cost. If you’re planning to use a device other than as a hygrometer, then there’s no harm in investing in them. But if you’re only using it for checking humidity levels, the practical route is to stick with a simple hygrometer.
Are hygrometers accurate?
One of the biggest questions that we usually get pertains to the accuracy of hygrometers.
Generally, hygrometers are quite accurate. A margin of error of 3% is already quite decent, and anything beyond that should be bought with caution. This is to make sure that your guitar will be safely stored in a place with the recommended humidity level.
Nevertheless, some experts believe that digital hygrometers offer better accuracy than their analog counterparts. This is due to the more advanced hardware used in these digital devices.
But we have come across analog hygrometers that delivered fairly accurate readings. The only downside is that these devices need frequent hardware calibration to maintain accuracy.
So overall, yes, hygrometers are quite accurate. As a tip, make sure to look into the unit’s margin of error before you buy it to ensure the best performance.
How to test hygrometer accuracy?
If you still have doubts as to the accuracy of your device, there is an easy way to test it out. All you need is a lockable food storage bag, a bottle cap, some salt, and a little bit of water.
To start the test, simply fill the bottle cap with salt and add a little bit of water. It should only create a slurry-like substance with the salt not fully dissolved.
With the salt slurry ready, place it inside the food-storage plastic bag with the hygrometer and seal them together. Leave this for six hours.
Once the 6-hour limit is up, it’s time to check the reading on the hygrometer. If the reading is at 75%, then you know it’s calibrated to accuracy.
Another test is to wrap the hygrometer with a damp towel and leave it for around 30 minutes. Once the time’s up, quickly unwrap the towel and read what’s displayed on the hydrometer. You should do this fast because the humidity levels will quickly drop once the towel’s removed. If the hygrometer reads between 98 to 100%, then your device is pretty accurate.
As a tip, we suggest performing any of these tips at least once every six months to make sure that your hygrometer remains accurately calibrated.
Frequently Asked Questions
What is the best humidity level for guitars?
The humidity levels for a guitar should not drop below 40% but should not exceed 55%. When it goes lower than this range, the wood tends to become brittle and prone to cracking. On the other hand, too much humidity can soften the wood – and similarly lead to damage.
Are digital or analog hygrometers better?
It depends on your preferences. Digital hygrometers are generally more accurate and easier to read, thanks to their modern hardware and technology. They also offer multiple features such as temperature reading and a clock. However, these digital devices can come with a steep price.
On the other hand, analog hygrometers are affordable and less complicated to use. However, they are high maintenance and would require frequent recalibration to ensure accuracy.
Where does the hygrometer go in a guitar case?
It is recommended to put the hygrometer inside the guitar case compartment or in the headstock for accurate readings.
Are hygrometers only for acoustic guitars?
No, hygrometers are not only useful for acoustic guitar but also beneficial for electric guitar. Most of us only think of acoustic guitars when addressing humidity issues, but particular electric guitars are also prone to damage from high and low temperatures. So humidity check and humidity control are also needed for some electric guitars depending on the wood quality.v
How long does it take for a hygrometer to get an accurate reading?
Hygrometers usually take around two hours to stabilize their readings. These devices have to consider several factors in the air, so this time frame is enough to deliver accurate readings.
To conclude, accuracy is the number one determinant to help you find the best hygrometer for guitar. After all, the goal is to preserve and ensure its longevity, so you can’t risk it on a device that won’t deliver.
Also, keep in mind that the purpose of a hygrometer is to inform you of inadequate or excessive moisture in the surrounding air.
Lucky for you, the items we have listed are proven to be accurate and serve the purpose well. And if you need help in narrowing down your options, you can always consult our buying guide for extra information.
