How We Chose and Tested the Best Hygrometers
Testing how accurately the above hygrometers measure humidity required us to calibrate each device before we could do anything else. This YouTube video details the process, but the short synopsis is that we put a small amount of salt and hot water next to each hygrometer in an airtight container and left them alone in a closet for 24 hours. We then checked their readings and determined how accurate they were. We adjusted the models that allow calibration and noted how far off the other units were.
We then tested each unit over for at least 5 days and as long as several weeks, setting them up next to each other indoors, outdoors, and in the bathroom after showers. We kept handwritten logs and downloaded dozens of CSV files, checking for quick response time to changing conditions and overall accuracy regarding humidity and temperature readings. For Bluetooth and Wi-Fi units, we monitored connectivity at half range and maximum range, noting whether walls affected accuracy.
What to Consider When Choosing a Hygrometer
Beyond HVAC efficiency, maintaining proper humidity levels can improve health by helping to keep sinuses clear and making it easier to breathe. Accurate humidity control is also essential for protecting wine, cigars, plants, and keepsake items.
Choosing the best hygrometer requires careful consideration. Begin by determining where you will use the device, as indoor and outdoor hygrometers will have different features. Then consider whether you need advanced features like smart connectivity, unlimited data storage, or extended battery life—or if simply knowing the current conditions is all that matters.
Types of Hygrometers
Hygrometers come in several variations, but each is effective at sensing and displaying the humidity in a given environment. While the most popular hygrometers are electrical or mechanical, dew point hygrometers and psychrometers are worth learning about to appreciate the science behind these instruments.
Keep in mind that many hygrometers also display the temperature to serve as indoor thermometers as well. This can be particularly helpful in food storage spaces or wine cellars.
Electrical
Electrical hygrometers are the most widely used and high-tech hygrometers available. These devices measure the changes in electrical resistance across a semiconductor or sensor that reacts to the air’s moisture content. As the moisture content changes, the resistance increases or decreases, which the hygrometer displays digitally.
Today, most electrical hygrometers use batteries for power. Several models have Bluetooth connectivity, allowing users to check the hygrometer’s readings from the convenience of their smartphone. Others may operate on the home’s Wi-Fi, alerting the user to the conditions in the home so they can run a humidifier or dehumidifier to adjust the levels.
Mechanical Hygrometers
Anyone who’s perused the tables at a child’s science fair has probably seen a mechanical hygrometer. This popular science project uses the changes in organic materials caused by moisture content to display humidity levels.
In their simplest form, mechanical hygrometers use organic materials like oxgut or human hair to control a needle that points to a humidity scale. When the moisture content in the air rises, the organic material absorbs the moisture, contracting and becoming heavier, which in turn raises the needle. As the air dries, the material becomes lighter and stretches a bit, allowing the needle to fall.
Dew-Point Hygrometers
Moisture condenses on the polished-metal mirrors of dew-point hygrometers. By noting the air temperature at which water begins to condense on the mirror, experimenters can determine the dew point. To provide accurate readings, these devices require extremely consistent conditions, including constant atmospheric pressure and constant vapor content.
Dew-point hygrometers are very old-school technology, with the first invented in 1751. They aren’t used much, if at all, anymore, but modern hygrometers owe a bit of credit to this early device.
Psychrometers
While psychrometers don’t adorn the windows of many kitchens or greenhouses, they are still in use in meteorology. They’re also popular in wildland firefighting for detecting the danger and potential for a fire.
Psychrometers use two types of thermometers to measure the air’s moisture content. It’s a rather complicated process that involves wrapping one of the thermometers in a wet cloth and spinning both thermometers. The experimenter then enters the readings from the thermometers into an equation to determine the humidity level.
Application
How you intend to use a hygrometer makes a significant difference when choosing the best model. For instance, users may want a different product to monitor the humidity level of a greenhouse than to check on the conditions inside a reptile tank.
For most situations, a digital hygrometer that users can place on a bookshelf or table will serve just fine. However, some might prefer a minuscule hygrometer or one that operates without a battery for niche needs and applications.
Accuracy
On the whole, hygrometers are relatively reliable and consistent instruments. The most accurate hygrometer models are within 5 percent of true values. Beyond that, accuracy comes down to calibration.
Folks who suspect their hygrometer’s accuracy might be off a bit need to calibrate it. They can purchase a hygrometer calibration kit, which requires placing the hygrometer in a sealed bag for a prescribed length of time. The hygrometer reading relative to the kit’s percentage will determine if it needs calibration. Digital hygrometers may have calibration knobs or reset buttons, smart hygrometers are typically easy to adjust via app, and most analog hygrometers have adjustment screws in the back.
Digital vs. Analog
When it comes to reading a hygrometer quickly from a distance, it’s hard to beat an analog hygrometer. These mechanical hygrometers have needles that point to the general range on the dial, which is all folks need in most scenarios. The drawback of an analog dial is that it’s hard to tell the exact reading even up close, and these devices cannot measure more precisely than a full percent, while digital hygrometers can measure a tenth, hundredth, or even a thousandth of a degree. While this level of precision isn’t necessary for most users, it may be for some.
Digital displays are the choice to go with when it’s important to know the exact value of the humidity. With an electric hygrometer’s digital display, if the moisture begins to change, users will likely notice it sooner and more easily. The numbers will change as opposed to tiny movements from a needle. The downside is that low-quality or small digital displays can be challenging to read, as some digits can be hard to decipher from one another from a distance.
Power Source and Battery Life
Some countertop-style hygrometers come with 110V electrical adapters that plug into an outlet for unlimited runtime, although most run via battery power, with battery life lasting 6 months or more. Some models use rechargeable batteries, which can be particularly handy as long as the battery life lasts for a significant period of time.
Longer battery life may be especially important for remote monitoring using Wi-Fi or Bluetooth-enabled devices. For instance, when tracking plant humidity in a terrarium that needs to be kept closed as much as possible, it’s important to get a terrarium hygrometer sensor that’s thrifty with battery life.
Remote Monitoring and Alerts
Monitoring humidity levels isn’t always about personal comfort or convenience. Sometimes, it’s required by a favorite hobby or pursuit. For instance, monitoring a wine cellar or cigar humidor’s humidity level can be the difference between maintaining a wonderful selection or spoiling an expensive collection, and some wood musical instruments require precise humidity levels to avoid cracking that will destroy them.
For help keeping these areas within a crucial humidity range, it’s worth purchasing a hygrometer that relays data to a smartphone or a remote display. Most important, perhaps, is the ability to set a particular range and send alerts when the humidity is outside that range, which can help users take action before their cache spoils or molds.
Interconnectivity and User Interface
Thanks to advances in Bluetooth, Wi-Fi, and smart-home technology, there are plenty of options for connecting a hygrometer with personal technology.
Many of these devices use their own apps, allowing users to monitor the humidity levels via Bluetooth from a smartphone. This can be a great help when trying to avoid opening a sensitive environment like a greenhouse or terrarium. However, be aware that not all apps are equal in usability and function, so check into this before deciding on a compatible hygrometer.
From a smartphone, hygrometer users can access temperature and humidity readings in their homes when they’re not even there by using a WiFi-enabled app. Some of the best hygrometers can interact with smart-home devices, too. They provide their readings via Alexa, Google Assistant, or other digital assistants. If the user can access a home thermostat from their smartphone, they can adjust the home’s temperature settings based on information from the hygrometer’s app.
Data Logging
Those who are serious about controlling the humidity in their homes for health reasons, hobbies, or any other purpose need to collect data. They might want to consider a hygrometer that keeps a log of humidity values and temperatures. They can track that data and stay ahead of seasonal or environmental trends, maintaining a more consistent environment.
Some devices keep data logs in their apps, so users will have up to 2 or more years’ worth of information at their fingertips. Even more helpfully, they can export a spreadsheet of this critical data, which they can then store on a computer or print out.
FAQs
If you have condensation on windows or need to increase humidity for sinus health, answers to the following frequently asked questions might help you use a hygrometer to keep air vapor levels appropriate.
A main living area is usually the best place for a hygrometer. Moisture created by a kitchen or bathroom can temporarily make your house very humid, so it’s best to keep your hygrometer in a dryer room unless you’re specifically interested in managing the humidity fluctuations near those rooms.
Using a calibration kit, you can determine how far off your hygrometer is before calibrating it. Analog hygrometers have adjustment screws in the back of the gauge that you can manipulate to adjust the reading. Digital thermometers have adjustment knobs that you can dial to the proper humidity level. Smart hygrometers are generally adjustable via app.
If you need to add some moisture to the air, you can use a humidifier, which emits water vapor into the air. If you need to decrease your humidity levels, even a small dehumidifier will help. These machines pull air in, remove the moisture, and release the dryer air into the environment.
To check if your hygrometer is working, place it in an airtight container with a bottle cap full of salt and a small splash of water. After several hours, you should notice a difference in the hygrometer’s readings.
Indoor relative humidity should ideally be kept between 30 and 50 percent. If you live in a dry climate or you notice the air needs more moisture during certain seasons, using a room humidifier can help. If you need help getting humidity levels lower, check out the tips in our guide on how to lower humidity in your house.
