Best Hygrometer

Controlling a poor level of humidity in a building, room, or enclosed space can drastically impact your health, disrupt your storage conditions, or destroy expensive possessions. Are you needing to monitor your home’s humidity levels? Maybe you have to take care of some animals at your home? Perhaps you operate a greenhouse? Or maybe you want to ensure your cigars are kept in pristine condition 24/7?

Whatever your reason is for maintaining humidity levels in your home, making sure you can measure the relative humidity is essential. 
Your best bet for measuring humidity is by using a hygrometer.

What Is a Hygrometer?

A hygrometer is a device that measures the level of humidity in the atmosphere. Also known as a humidity meter or humidity gauge, hygrometers measure the amount of moisture in a specific environment. It does this by calculating changes in pressure and temperature.

There are a number of different types of hygrometers, including digital (also known as electrical) hygrometers, mechanical hygrometers, psychrometers, and dew point hygrometers. 
Digital hygrometers are the most commonly used hygrometers. They’re most often used in greenhouses, industrial premises, and other outdoor environments, for fast and accurate humidity readings. There are a few different types of personal and indoor-use humidity meters that are used for keeping food storage areas moisture-free, monitoring wine cellars, and preserving cigars.

In this article, we’ll take you through the best hygrometer on the market. We’ve analyzed the top hygrometers available to give you an accurate picture of what one is best for you. We’ve also included a buyer’s guide at the bottom to paint a picture of what you should expect from the best hygrometer today.

What we like?

One of the upgrades this AcuRite hygrometer has on the first model is the humidity level indicator. While the earlier model has a humidity level indicator, this one is much more user-friendly. This indicator is color-coded, making it very easy to see when the humidity is in or out of the proper range.

Another advantage of this digital hygrometer is that it can be manually calibrated. This means you’ll be able to increase the accuracy of the hygrometer even better than the model at number one.

What We Don’t Like

While this digital hygrometer is an upgrade on the AcuRite at number one, it has two drawbacks. For one, there isn’t a backlight which can be annoying, especially when you’re trying to fumble over to your hygrometer at night.

Another downside is that it doesn’t show the numbers to the tenth decimal. It only shows them as whole numbers. So if you are wanting a hygrometer that shows readings accurate to the decimal point, you’ll want to pick a different one.



  • Very accurate
  • Color-coded humidity level indicator
  • Manual calibration
  • Daily high and low readings

● No backlight
● Shows numbers as a whole, not to a tenth decimal

Next up on our list is the ThermoPro TP63A Waterproof Indoor Outdoor Thermometer Digital Wireless Hygrometer. If you’re wanting a hygrometer that offers a two-in-one solution for the inside and outside of your home, then this might be the best hygrometer for you.

What we like?

The ThermoPro hygrometer is technically two separate hygrometers. The indoor hygrometer is the main device that features the LCD display, while the outdoor device is simply a secondary reader without a display. You can view both the indoor and outdoor data on the indoor hygrometer simultaneously.

The outdoor hygrometer and thermometer is completely sealed and includes a rechargeable lithium battery.

You can also purchase additional outdoor sensors and sync up to 3 outdoor sensors at a time to the main indoor device.

What We Don’t Like

The main downside to this hygrometer is the fact that you have to keep recharging the outdoor sensor every now and then. Thankfully, it comes with a USB charger and can be easily charged right from your PC or laptop. It’s also a bit more expensive than typical hygrometers.

  • Smart hygrometer
  • View data from smartphone
  • View recent data records
  • Smartphone notifications when humidity or temperature is outside the proper range
  • Smartphone data only accessible through Bluetooth, not wifi

If you want a hygrometer that will simply get the job done and don’t want to spend a lot of money, then this might be the best hygrometer for you. The Habor Hygrometer Indoor Thermometer, Humidity Gauge is a solid device that works well for anyone who needs a hygrometer for everyday use.

What we like?

The device isn’t fancy. It doesn’t have a ton of bells and whistles. However, this hygrometer by Habor is solid. It gets the job done. It shows the stats that matter the most: temperature and humidity.

Even though the device is on the smaller end, the display is quite large, making it easy to read from afar.

What We Don’t Like

The main advantage to the Habor model is its main disadvantage. It’s simple. It only shows temperature, humidity and a smiley face depending on if the levels are in the right range.

If you want daily readings, highs, lows, or any other features, you’ll want to look elsewhere.



  • Budget friendly
  • Large display
  • Simple
  • Doesn’t show daily highs or lows
  • Doesn’t show trends

If you’re looking for something a little more “vintage”, then you’ll want to consider the Cigar Oasis Analog Hygrometer by Western Humidor. This is one of the best analog hygrometers on the market today. It’s a great mechanically-operated hygrometer that was specifically designed to preserve cigars.

What we like?

The Cigar Oasis Analog Hygrometer has incredible accuracy, to a degree of plus or minus 1 percent. You can also manually recalibrate the hygrometer whenever you like to match your standards.

The hygrometer also has a high-quality build. It has a corrosion-resistant aluminum case, a scratch and fog resistant glass face, and includes a secure magnetic mount.

This cigar hygrometer includes three day high and low averages for both temperature and humidity to ensure you can keep a good watch on your cigars.

What We Don’t Like

It’s not pretty. It’s not vintage. The looks won’t impress your friends when you open up your cigar case. But, this device wasn’t made for the looks. It was made to work, and that’s something it does well.

It’s also not the cheapest hygrometer on the market. It’s not extremely expensive, but there are definitely cheaper options available.



  • Ranked the most accurate hygrometer in cigar industry
  • Secure magnetic mount

Best Hygrometer Buyer’s Guide

As mentioned earlier, a hygrometer is a device that measures humidity or the moisture level in the air at any given time.

Hygrometers can be used for a variety of reasons, though their function is specifically to measure the humidity. Something important you should consider about hygrometers is that they aren’t meant to adjust or regulate temperature or humidity levels. Their main purpose is to simply tell you what the current state is.

So what are hygrometers used for the most?

Cigar Humidors

One of the most popular uses for hygrometers is for cigar enthusiasts. In order to keep cigars fresh, you have to ensure they are stored properly. Cigar enthusiasts will buy a wooden box called a cigar humidor to store their cigars in. These wooden boxes are meant to maintain humidity levels despite external conditions.

Cigar humidors allow cigars to stay fresh and maintain a certain moisture level. This is crucial since tobacco leaves that contract or expand depending on the level of humidity in the air around them.

What Else Are Hygrometers Used For?

Hygrometers aren’t just used for cigar humidors. There are a variety of reasons people use them:

  • Maintaining humidity in a specific room for medical reasons
  • Minimizing humidity to prevent mold growth
  • Ensuring an animal or pet’s environment is kept in stable condition (generally reptiles)
  • Reducing risk of asthma-inducing agents including dust, fungi, and other viruses and bacteria
  • Protecting expensive equipment including wines from being ruined by excess humidity

Digital & Analog Hygrometers

There are two types of hygrometers: analog and digital. Analog hygrometers are the “traditional” hygrometer type that have been used for centuries to measure humidity. These are usually crafted with a metal frame, and include a face similar to a watch that includes arrows that point to certain numbers in a wheel to designate the metrics.

Oftentimes, cigar humidor containers will already feature a built-in analog hygrometer. However, although analog hygrometers may give off a “vintage” feeling, they are generally less accurate than digital hygrometers.

Though they offer a better appearance, analog hygrometers are also harder to calibrate.

Digital hygrometers offer a much more accurate picture of the humidity levels in your room or humidor. Nowadays, digital hygrometers also double as a thermometer, and may even give you daily averages, or historical data.

The most advanced hygrometers will even connect right to your smartphone through an app so you can read the data right from your mobile phone.

We hope this extensive guide helped to find the best hygrometer for your needs. Any suggestions or questions, let us know below!

    The thermopro t50 does not reset the high/low values daily, they reset only when the battery is replaced.

    I’m in southeast Texas 40 miles from the Gulf of Mexico. Humidity is a concern most of the year inside and out. I just had an Aprilaire dehumidifier installed to try to get a handle on what my A/C leaves behind in the air. Estimates are that average residential central air in this area produces 12-20 gallons of condensate a day in summer. In spite of that removal, my indoor humidity (according to the Honeywell thermostat readings) is usually in the 50-57% range with the A/C set to 75 degrees.

    I bought the ThermoPro TP50 and two of the AcuRites. In addition I have an older ThermoPro indoor/outdoor and two Honeywell thermostats (upstairs and down) that display RH. Discounting the Honeywell downstairs, I had five near each other and compared. Five reported 38, 42, 43,43, and 45. Those are the old indoor/outdoor, the two AcuRites, the Thermopro TP50, and the upstairs Honeywell. Since the AcuRites are the only ones that can be “calibrated”, I adjusted one of them to match the other and the ThermoPro TP50. I stuck the two AcuRites to the Honeywell thermostats with double sided foam tape, so when I look at the thermostat, I have a second opinion right there. The TP-50 is my portable to see how certain areas compare–bedroom overnight, home office, TV room.

    I think the digital displays imply a level of accuracy that doesn’t exist unless you have hundreds or maybe thousands to spend. Probably the best accuracy these should display is very dry – dry – moderately dry – optimum – moderately humid, – humid – very humid. No numbers at all.

    And I have enough stuff dependent on my phone, so I ignored the bluetooth models. Might change my mind though, as I saw a variation on the Temp Stick idea with four sensors.
