Reasons to purchase a hydrometer
There are multiple reasons for which you may want to purchase a hygrometer, with the most important of them being to improve the quality of air in your home. With the help of a hydrometer, you can measure how much water vapor is present in the air you breathe so you can decide whether you need to dehumidify or humidify a room according to your personal needs.
Using a hygrometer is a good way to reduce energy consumption if you’re using a humidifier, as you can turn it off when the desired level of humidity is reached.
You may also need a hygrometer for specific activities, such as when you want to keep track of the level of humidity in the air in a room where you keep your musical instruments such as guitars, or when you want to make sure the humidity is just at the right level to store your cigars correctly.
Things to consider before getting a humidity sensor
Before deciding what type of hygrometer you need, it’s important to take into account a couple of essential factors, such as areas where you intend to use it, the humidity and temperature range you need it to track, accuracy, alerts and indicators, data updates for smart models, power source, dimensions, and other functions you might be interested in. Finally, don’t forget to consider your budget to be able to find a model in your price range.
To purchase the best hygrometer for your needs, it’s important to first decide what those needs are. Some of the most common applications for hygrometers include monitoring the humidity and temperature in the home, in a guitar case, or in a terrarium, so your reptiles are happy and healthy. Other people need hygrometers for their cigars boxes, so their favorite cigars don’t get ruined by the wrong level of humidity. Consider what type of application you need before deciding which model is right for you.
Hygrometers show humidity in percentages, and many models, including smart ones, such as the SensorPush Wireless Thermometer/Hygrometer, can measure humidity from 0 to 100%. But, some hygrometers, such as the Veanic Mini Digital Electronic Temperature Humidity Meters, for example, only go from 10% to 99%, so it’s important to know what range you’re looking for to make sure that the hygrometer you choose can provide the right measurements for you.
Just like in the case of humidity, hygrometers have different ranges as well when it comes to measuring temperature. Our editor’s choice, the ThermoPro TP50, measures temperatures between -58°F and 158°F, but other models may not have the same range. In most cases, you can switch between Celsius and Fahrenheit scales with a click of a button.
As you may have already noticed, accuracy is highly important when it comes to hygrometers, so if that’s essential for you (for preserving musical instruments or cigars, for example), make sure you go for a device that checks both humidity and temperature with the highest accuracy possible. An example of a highly accurate hygrometer is the Cigar Oasis Caliber IV Digital Hygrometer, which measures those parameters within ±1%RH and ±1℉.
Alerts and indicators
The best hygrometers, particularly the smart ones that you can connect to your phone via an app, offer remote monitoring, indicators, and alerts. This means that you can monitor your device remotely, which is useful if you’re interested in being able to protect your belongings when you’re not at home.
You can set up most smart hygrometers to send you alerts when the humidity or temperatures are off the charts.
Even though many users may not be interested in data logging, if you want to have access to past data for statistical purposes, you should look for a model that has data logging capabilities. Some hygrometers log minimum and maximum ranges for up to 30 days, and you can have access to even more data if you’re using the app on your mobile phone.
Number of units in the package
If you need more than one hygrometer, it’s a good idea to look at products that come with more than one in a package. Examples include the Veanic Mini Digital Electronic Temperature Humidity Meters and the Ambient Weather Wireless 8-Channel Thermo-Hygrometer. These models come with four hygrometers per pack, so you can place one in every room of the house where you want to monitor humidity and temperature.
Most hygrometers are battery-powered, so it’s important to choose a model that works with the type of battery you want.
You should make sure you check the description of the product to determine the battery type and its expected life.
Keep in mind that models that use wireless connectivity, such as the SensorPush Wireless Thermometer/Hygrometer, for example, will drain the battery quicker because they have to send signals to your smartphone continuously.
The dimensions of the hygrometer are essential when it comes to placement. Decide where you want to set up the hygrometer, make sure it fits. Some models, such as the Cigar Oasis Caliber IV Digital Hygrometer, for example, are compact enough to fit in a cigar box, whereas others, like the Extech Humidity Alert II, are much larger but come with the added advantage of sporting a large LCD display that’s easy to read.
What else can be important?
Other features that you can expect to find in some hygrometers include Bluetooth and Wi-Fi connectivity, which are great if you want to be able to monitor the humidity and temperature in a designated space with the help of your smartphone or computer. Bluetooth connectivity allows you to receive alerts from the hygrometer when the ranges are not within the normal limits. Another thing that it’s important to look for is the NIST certification, which is the nationally recognized calibration standard for hygrometers.
The prices for hygrometers vary greatly according to their functionality and accuracy. You should expect to pay more for a smart model with smartphone connectivity and the ability to monitor humidity and temperature remotely. These should cost anywhere around $50 or more. Simpler options are much cheaper, and you can easily find reliable options at about $15.
