Grow rooms require constant monitoring, as the health of plants is directly dependent on the environmental conditions. If the medium is too dry or too hot, the leaves can easily develop diseases linked to dehydration, while a high level of humidity can facilitate the growth of mold or cause the plants to rot. In this case, the most appropriate choice is a model that can stand the humidity conditions of a growth room while providing correct information. AcuRite 01083 can measure humidity values ranging from 1% to 99% with an accuracy of +/-2%, so we can easily place it among the most precise on the market. Moreover, it can collect data about the indoor temperature as well, with a span of -4 to 158 degrees F and precision of +/-0.5 degrees F. The measurements are made every 10 sec., so the results are always fresh from the field.

It features a large LCD, which is divided into two sections. On the top side, you will find the relative humidity value and the min and max of the day, while the bottom side shows the temperature and, once again, the minimums and maximums. It uses arrows to show the trends for both parameters. Plus the extremes of every day are stored, so you can get an accurate perspective on the parameter variations over time. In the middle of the screen, you will find a humidity level indicator, which uses 3 colors to indicate room conditions. Thus, if the blue LED is on, it means you will need to increase the moisture in the air. If the indicator is red, the moisture in the air is too high and your house is at risk of developing mold. Nevertheless, when the green light is on, it means everything is perfect and you can just enjoy your comfort.

Apart from the fact that it can be easily calibrated at home, as the instructions are clear and easy to follow, its popularity is increased by the three mounting alternatives.

If there’s a place in the house in need of a high-quality hygrometer, it is the basement. As it is placed underground and, thus, poorly ventilated, this space in the house is more prone to develop mold and bad odors. Moreover, the lighting is usually a problem in basements as no large windows are available to let the light in and, as no one is spending a lot of time there, the artificial lighting source is usually poor. In this case, the use of a device that can measure humidity with accuracy and display it on a large screen with tall characters is mandatory, and this model from ThermoPro meets all the requirements. First of all, the LCD screen is one of the largest you could find in these instruments and is backlit, so the information is available no matter if you place it in the darkest corner or try to read it with the light off. Nevertheless, despite the huge screen, the unit remains compact, measuring only 4.3 inches in height, 3.3 inches in width, and only 1 inch in depth.

In terms of accuracy, we have appreciated that it is one of the most precise in its class, as it offers an RH precision of 2% to 3% for a humidity range of 10% to 99%. The temperature readouts are reliable as well, as the maximum deviation doesn’t overcome +/-1 degree F. In this case, the measuring range is -4 to 158 F for indoor. Worthy to mention, it can be used for outdoor measurements as well. It collects new data every 10 secs and can be programmed to display temperature values either in Celsius or Fahrenheit. Plus, it stores minimums and maximums for every day, allowing you to keep track of the variations from the past days, and previsions the trend through arrows, allowing you to take measures before temperature or humidity reach critical values.

The touch screen is straightforward and allows for easy configuration. Besides that, it offers 3 mounting methods that make it highly versatile. Thus, you can place it on a shelf or a table, as it comes with a built-in stand, hang it on the wall, or stick it on the fridge, as it includes a magnet for this purpose. Not to mention that, in terms of warranty, this brand is super generous, offering 3 years for repairs and parts, and knowledgeable and friendly customer support for 5 days a week.

What we like:
  • Large backlit touch screen is easy to read in the dark and user-friendly
  • Accurate readouts for both temperature and humidity
  • Three mounting methods
  • Excellent 3-year warranty
  • Trend arrows allow you to preconize dropouts or growths in humidity and temperature and make adjustments before critical values are reached
What we dislike:

✖ Although it is advertised as an indoor-outdoor unit, it is efficient only indoors

Verdict

This is a solid model with plenty of options and comes at a great price, so it is totally worth the investment. The jumbo touch screen with the backlit option is a nice addition as it allows for distance reading. Plus, it can store min and max values for the previous days and uses arrows to indicate the trend for the following hours, so you will not have to wait for the parameters to reach critical values to adjust your appliances.

Furthermore, as it comes with a stand and a bracket, you can choose either to place it on a table or shelf or hang it on the wall.

Premium Features

The solid structure is just one of the criteria that made us place it in the first position. We surely have appreciated the paint that makes the housing more durable and the high-quality materials that were used to its construction. Nonetheless, what impressed us the most was its versatility and convenience provided by a strong set of premium features:

  • Remote probe – makes the measuring even more accurate by extending the area 18 inches behind the walls
  • Audible alarm – activates when the minimum or maximum humidity value set by you is reached
  • Min/Max storing – the memory will store daily maximum and minimum values, for easier humidity tracking
  • Generous LCD screen – allows for simultaneous display of temperature, humidity, and dew point in large letters and numbers that can easily be read from the distance

The DEW point is a great addition that is rarely provided with a hygrometer. It represents a calculation of humidity and temperature that will allow you to know when condensation will happen. Thus, you can act against it by speeding up the dehumidifier, the air conditioning, or the fan and prevent mold from forming on your walls. For calibration, it features an adjustment pot and a reset function. Nevertheless, for field calibration, you will need to purchase the optional calibration kit. Besides that, with a 1-year warranty being offered by the manufacturing, you can put your mind at ease and test its accuracy.

What we like:
  • Audible alarms make it a great choice for environments where a strict RH range should be maintained
  • Remote probe allows for behind-the-wall measurements
  • Large LCD with backlit provides better visibility
  • Accurate readings
  • Tight construction
What we dislike:

✖ Calibration can be a bit tricky

Verdict

It offers the best combination between accuracy and price and comes with a solid construction that can stand the harsh conditions of a basement. The large LCD provides instant access to all the parameters, while the audible alarm can let you know when the humidity has become a threat to your home. Moreover, as it stores the min and max of every day, you can easily track your new dehumidifier and see if it works as it should.

Conclusion

No matter if you need to keep an eye on the humidity variations in your home and thus care for your family’s health or for specific activities that require accurate monitoring of the environmental parameters, an indoor hygrometer is always a great investment. As you have probably noticed, these devices are highly versatile and can easily match any space, but some are more accurate than others, while in some cases, the design adds value and makes the product more desirable.

Our ranking has focused on these 2 criteria while paying attention to the prices and warranty periods as well, so you can trust that the order reflects the quality of the products. Nevertheless, some models come with fewer functions but are more suitable for specific tasks, like monitoring a reptile tank or a box of cigars, so keep this in mind when making your decision.

If you haven’t found yet the perfect match, here are some models that deserve a second visit:

Best Indoor Hygrometer on the Market: Extech Instruments Digit 445815

If you are looking to do accurate measurements, this model is the closest you can get to a commercial-grade hygrometer. It is more on the expensive side, but a single look at its construction is enough to see that it will pass the test of time. It is equipped with a large LCD that displays not only momentary temperature and humidity values but the dew point. Moreover, it comes with a remote probe that can extend the measurements to up to 18 inches behind walls. Not to mention that it features an audible alarm, which will ring if the values chosen by you are exceeded.

Editor’s Choice: SensorPush Wireless HT1

If you are more into technology, this model can offer you total control from the distance, as it can send real-time data to your smartphone on a distance of 325 feet. Moreover, although this will be an extra expense, it offers the possibility to buy an add-on that can link it to the internet, so you can receive humidity and temperature readouts even when you are not at home. The small dimensions of the sensor make it suitable for musical instruments or cigar case monitoring, but the durable structure recommends it for reptile tanks as well, and even for controlled outdoor objectives.

Best Indoor Hygrometer for Reptile Tank: Veanic 4-Pack 8541833457

It is an excellent pick, especially if you are trying to monitor multiple terrariums or reptile tanks at the same time. The set includes 4 accurate units that can be set around the house in the desired places. They are compact and will pass unnoticeable. Nevertheless, the LCD is still large enough to provide temperature and humidity readouts in clear, tall characters. Not to mention that it is built of ABS, so it will stand tough conditions without a problem.

Best Indoor Hygrometer for Cigars: Cigar Oasis ACC-CALIBER IV

Not only compact but elegant and ready to match any cigar box, it is one of the most accurate in the cigar hygrometer industry. It arrives pre-calibrated but it allows you to recalibrate it if you consider it necessary. A secure magnetic mount allows you to place it on the inside of the lid, assuming that the box is made of metal. Moreover, as it comes with a slim profile, you will have no problem closing the lid so the cigars maintain their aroma and texture for longer.

Best Indoor Hygrometer for Incubator: EEEKit Hygrometer Thermometer Digital LCD Monitor

Another set with broad application, it will prove a clever pick for an incubator. The round shape allows you to slip it with the eggs while the round LCD screen focuses on displaying the humidity in large characters and the temperature in smaller ones. The measurements are accurate and refreshed every 10 secs, so you can rely on it to show only the most recent data. Besides that, although it arrives pre-calibrated, you have the possibility to reset it.

Best Indoor Hygrometer for the Money: ThermoPro TP50

A very popular choice among buyers, it manages to perfectly blend accuracy with a user-friendly design and a great price. The array of functions is complete, starting with the measuring functions and ending with high and low values and trend arrows. Furthermore, a quick face icon comfort display function was added, which, combined with the generous LCD, allows for easy reading from the distance.

Best Indoor Hygrometer for Grow Room: AcuRite 01083

As the name suggests, this is a highly accurate model that can successfully be used in a grow room or any other spaces with high humidity. The plastic housing prevents rust from entering the inner coils and thus extends its lifespan. Furthermore, the touch screen displays not only the current values but allows for a quick evaluation of the humidity levels through a color chart.
