The main criteria to pay attention to when choosing a hygrometer

Even when choosing a fairly simple device like a hygrometer, you need to know what to look for. So, here are the main criteria: 

  • Meets your moisture and temperature range needs

The first thing to keep in mind is where you intend to use the hygrometer. If it is for a refrigerator or a place where you keep your wine, you need to look at hygrometers that have a negative temperature range, as well as an appropriate humidity level. 

If you need a hygrometer with a wide range of temperature and humidity uses, pay attention to the ThermoPro TP50 (review) because it can measure both indoor and outdoor conditions. It’s accurate, reliable, and has a large screen that makes it very easy to use. Also, it can measure the temperature from -58°F to 158°F. The Govee Smart Hygrometer Thermometer (review) will also be helpful as it has the biggest humidity range (0% ~ 99%) but it has a smaller temperature range (-4°F – 140°F).

  • Max and min temperature and humidity

The second point is to understand whether you need readings of maximum and minimum humidity and air temperature. They will help you compare the current climate in your room with the highest and lowest readings. For example, with the memory of high and low humidity, you can monitor your needs with a humidifier. Some models give these values relative to the time from when they are plugged in, and some read them every 24 hours. Be careful when choosing.

You can change the amount of elapsed time of the temperature and high/low humidity from 24hrs to all-time if it is the ThermoPro TP55  (review) or the Govee Smart Hygrometer Thermometer (review). The temp and humidity (RH) maximum and minimum readings are all-time (for the whole period of use, not only the last 24 hours) in the ThermoPro TP50 (review). This means if you want to see nighttime lows, and daytime highs, you have to remove the battery daily, and that is not convenient.

  • Screen

The digits and readings must be easy to read, as most of the time you will look at them from a distance. From our top-list, the Habor Hygrometer & Indoor Thermometer (review) has the biggest digits that are the same in size as the readings of temperature and humidity. The ThermoPro TP55 (review) has the most readable values not only of temperature and humidity but also their max and min values. 

Not only does the size of the digits matter, but also the brightness and quality of the screen. The Govee Smart Hygrometer Thermometer (review) has an LCD indicator that is a little dim but readable at an angle, as mentioned by many users in their reviews. An additional feature is that you can pair this hygrometer with a phone via Bluetooth through the GoveeHome app and you can see the data from the app. 

Note: The Govee app has flashy adverts for other Govee products. 

  • Stand type: magnet, hook hole, or a kickstand

Multiple mounting options. This affects the convenience of installing the hygrometer for any type of room, such as the kitchen, music room, children’s room, office, etc. As a rule, the most commonplace for this is the kitchen. All presented models (except the Govee Smart Hygrometer Thermometer (review)) have a magnet, so you can install them on any metal surface like a fridge.

Benefits:✅ Has a backlight;
✅ Easy to control with a touchscreen.

Pros:

  • 4” large LCD touchscreen
  • Has a backlight
  • Ideal for monitoring up to different locations, such as cigar humidors, wine cellars, greenhouses, musical instrument cases, and more
  • Updates the reading every 10 seconds like the Habor Hygrometer & Indoor Thermometer (review

⛔️ Cons:

  • Does not show the humidity level under 10%
  • The backlight stays on for 15 seconds only

The ThermoPro TP55 is an ideal hygrometer if you plan to put it in a dark place. The 4” large LCD touchscreen with a backlight makes it ideal for a cellar. With just one touch of the button, you can activate the backlight for around 15 seconds. The backlight provides enough time to look at one indicator but not enough to analyze all of them. No worries, you can turn it on again. Also, the size of the digits is large enough to read them from a distance during the day.

As the Habor Hygrometer & Indoor Thermometer (review), this model updates the reading every 10 seconds. So, the readings will always be up to date. Pay attention that this hygrometer does not show a humidity level under 10%, however, you are unlikely to need this indicator in everyday life, as even in granaries, the humidity reaches 8-15%. Like all of the hygrometers, this one also has an Air comfort indicator. It has 3 levels: 

  1. Dry (humidity is below 30%)
  2. Comfort (humidity is between 30-60%)
  3. Wet (humidity is above 60%)

Benefits:✅ Has a 1-year warranty;
✅ It will work with one battery for up to 2 years.

Pros:

  • Daily high/low humidity and temperature
  • The temperature is almost as accurate as in the ThermoPro TP50 (review)
  • Has a 1-year warranty
  • The display is easy to read but it does not have a backlight like in the ThermoPro TP55 (review

⛔️ Cons:

This hygrometer has the best memory for temperature and humidity indicators. The AcuRite 00613 remembers data only for 24 hours but shows the most accurate reading. It is perfect if you want to check the values every day to analyze the tendency. For comparison, the ThermoPro TP50 (review) shows min and max values only for the whole time of use ( for the period from installation to the current date). This means that you only have to compare your current readings with the previous ones but not necessarily build a daily trend. Remember that for maximum accuracy, you should put the hygrometer in a dry area that is free of dirt and dust, out of direct sunlight, and away from any heat and humidity source. 

Another great advantage of the AcuRite 00613 is its 1-year warranty. It is the only hygrometer in our list that has it. But it also has one small disadvantage. This is the only hygrometer that does not come with batteries. However, this is not a problem as you need only one AAA alkaline battery and it will last you up to 2 years.

Some tips and tricks

How to check the accuracy of a hygrometer

There are special kits for home use, that are mess-free, and ready-to-use for checking the hygrometer’s reading:

Boveda for Cigars One-Step Calibration Kit 32%

Simply place your hygrometer inside the bag and completely re-close the zipper. Allow the Calibration Kit to sit for a minimum of 24 hours at room temperature, 65 to 75°F. The hygrometer should read the RH% level stated on the Calibration Kit. If not, note the difference for future readings or adjust your hygrometer if applicable.

The humidity level and your indoor hot tub

hOmeLabs 1,500 Sq. Ft Energy Star Dehumidifier

If you have an indoor hot tub, it is important to pay attention to the ventilation and humidity level in the room where it is located. Bathrooms usually have a ventilation system. But if not or if your indoor hot tub is located in a custom room, it is important to prevent condensation. That is why we recommend using a dehumidifier when the hygrometer shows a high level of humidity (more than 60%).

For more information on dehumidifiers and how to prepare a place for a hot tub, read our article.

Summary

A hygrometer is a fairly small yet essential device. It is useful because the right humidity level and air temperature are crucial for a lot of health-related concerns, as well as for keeping a check on the moisture level of your home. You can save a lot of money that would otherwise be spent on repairs for replacements of your home appliances.

When you decide to buy a hygrometer, pay attention to correct moisture and temperature readings, the ability to remember max and min temperature and humidity, screen quality, and some extras (such as a backlight, and type of stand- magnet/hook hole/kickstand). To check the accuracy of your hygrometer, you can use a calibration kit

FAQs

🤔 Can I do a salt test with table salt to check the accuracy of a hygrometer?

No, because table salt contains a lot of other things like various silicates, carbonates, iodine, etc. This makes the test inaccurate. Use calibration kits instead, for example, the Boveda for Cigars One-Step Calibration Kit 32%. You can find how to use it correctly in our article.

The ideal relative humidity (RH) for health and comfort at home is about 40–50%. But in the winter months, it is required to be lower than 40% RH to avoid condensation on the windows.

🧽 How to clean a hygrometer?

To clean your hygrometer, first, remove the cover or face. Wipe the glass with a soft, dry cloth. If there is any build-up on the glass, you can gently clean it with a cotton swab dipped in rubbing alcohol. Be sure to avoid getting any moisture on the sensor inside the hygrometer.
