Right out of the box, it is already pre-calibrated, which means that it is easy to use. Unfortunately, there will be no option to have it calibrated on your own.
Best Analog Hygrometer
#4 Cigar Oasis Analog Hygrometer Review
While this is made by a company that is known for hygrometers in the cigar industry, it can be used beyond such. At first look, it seems like a compass, but it is actually a handy device that manually measures the relative humidity in the surroundings.
This model is known as the most accurate analog hygrometer currently available on the market, so you can be confident about the functionality that it can deliver.
It comes with a secure magnetic backing, which will make it easy to install in the desired location. More so, when it comes to its construction, it is made of an aluminum case, which is good as it is lightweight and has the excellent ability to resist corrosion.

Types of Hygrometers
While there are many factors that are important to consider in your search for the best humidity meter, one that should be emphasized is the type that will work best for your needs. That being said, here are the options that will confront you:
Analog Hygrometers
Also known as a mechanical hygrometer, this is a traditional choice for measuring humidity. It is like a compass. There is a dial that points out to the number with the corresponding humidity level. They need regular tune-up or calibration. Otherwise, they can be easily prone to inaccuracy, especially after long-term use.
Digital Hygrometers
This is the more modern counterpart of the analog hygrometer. They come with a screen that automatically displays the humidity readings, refreshing at about every ten seconds. Most of the premium options can also double as a thermometer. They use modern sensors, which is why they are hard to beat when it comes to their accuracy.
The hygrometers can also be classified on the basis of their applications. Aside from the greenhouse, they can also be used for monitoring humidity at home to ensure everyone’s comfort and for cigar humidors.
Choosing the Best Humidity Sensor
To make it easier to narrow down the options for a top-rated hygrometer, here are some of the most important things that you have to take into account:
Accuracy
The first thing that you have to note is the accuracy of the sensor. It is important to choose one with accuracy 1 to 5%. This means that you can expect that the average readings will be right.
Ease of Use
The hygrometer also needs to be user-friendly. When it is taken out of the box, there should be no calibration required. Minimal effort should be needed on your end when it comes to care and maintenance. It should also have a large display that is easy to read whether it is day or night.
Multi-Functionality
A lot of the hygrometers that you can find on the market are designed not only for reading humidity levels but also for detecting temperature. For the best bang for the buck, pick a model that acts both as a thermometer and hygrometer.
Power Source
From the models that have been mentioned in this guide, they are powered by a battery. Take note of the battery that is used. Lithium-ion batteries are good since they will last for a long time.
Data Logging
This is an important feature if you would like to view the historical humidity data that the device was able to record. This can be useful in terms of checking the trends or changes in the environmental conditions.
Calibration
Not all hygrometers will offer the option to be calibrated by the user. Most of the digital options no longer need to be calibrated. Nonetheless, if you are using a model that requires calibration, make sure to adjust it from time to time to ensure that the readings will remain accurate.
Mounting Options
For versatility, you should pick one that offers several mounting options. Most of them will come with a magnet at the back. There are also many that can be mounted on the wall or simply be placed on the top of a stable base.
Durability
This is especially important if you are buying a hygrometer that will be used for outdoor applications. It should be made of premium materials that could withstand the test of time. Inferior construction can allow mist to easily infiltrate and can make the readings unreliable.
Wrap Up
To ensure the best humidity and ideal environment for growing your plants, whether it is an indoor or outdoor environment, the right hygrometer will be able to extend a helping hand. The products that have been mentioned above can be a big help when it comes to making sure that the moisture level is just right based on the needs of the plant at a specific stage of growth.
