Factors to Consider Before Purchasing the Best Hygrometers

1. Digital vs. Analog

How much you will enjoy your hygrometer will be determined by how easy it is to read it, and when it comes to reading a hygrometer quickly, an analog hygrometer might take the win. The analog hygrometers usually have a needle that points to the general range of the dial, and it is all you usually need in most cases. The analog dial’s drawback can be hard to tell you the exact reading, but also, the tiny changes in tenths of degrees can be impossible to detect.

On the other hand, digital displays are the most suitable choice for knowing the exact humidity value. With the displays of digital hygrometers, any change in moisture will be detected soon and quite easily because the numbers will change, unlike with the analog hygrometers where there are tiny needle movements. However, a digital LCD display, especially the small or low-quality ones, can be hard to read as some numbers are hard to decipher.

2. Application

How you will be using your hygrometer should determine the best one for you as it makes the whole difference. For example, checking the conditions inside a reptile tank would require a different hygrometer than monitoring the humidity level of a greenhouse. For most cases, a digital hygrometer that can be placed on a table will be ideal, but you may prefer a small or a hygrometer that does not need a battery for your applications and niche needs. Take into consideration your use of the hygrometer before you choose the one to buy.

Application for basic home use may not be as precise as the one needed for the cigar humidor.

3. Power Source and Battery Life

When using an electrical hygrometer, you need to ensure you are using the right power source for your needs to get the best results. Some hygrometers usually come with a 110-volt electrical adapter that you can easily plug into an electrical outlet, and some have a battery power option that can last for more than six months at a time.

The battery life is especially important for Bluetooth-enabled devices like monitoring a terrarium that you want to keep closed as much as possible. Some models usually use rechargeable batteries, and they can come in handy as long as the battery life can last for some time.

4. Accuracy

Hygrometers are usually generally consistent and reliable instruments, and most of them usually have a 5% accuracy. To get the best out of your high-quality hygrometer, you should ensure that your choice of hygrometer is within the accuracy range because beyond that, the accuracy will come down to calibration. Suppose you doubt the accuracy of a hygrometer. In that case, you should calibrate it by purchasing a calibration kit from your nearest store, and it will need you to place your hygrometer in a sealed bag for a specific period.

The hygrometer’s reading compared to the kit’s percentage should tell you if you need to calibrate your hygrometer. Notably, digital hygrometers usually have calibration knobs or reset buttons, whereas the analog hygrometers feature an adjustment screw in the back of your hygrometer.

5. Remote Monitoring and Alerts

Monitoring humidity levels can be for personal convenience or comfort, and sometimes it’s required with pursuit or a hobby. For example, when you monitor the cigar humidor, the humidity level can help you know the difference between maintaining or spoiling an expensive collection. It’s worth purchasing a hygrometer that you can check using a remote display or a smartphone to help manage and keep an area in a crucial humidity range.

6. Data Logging

Suppose you want to monitor and control your home’s humidity, whether as a hobby, for health reasons, or any reason, you should collect data. The best hygrometer, in this case, would be one that logs temperature and humidity readings, as this data will help you be aware of environmental trends and maintain a more consistent ambient weather environment.

Some of the best hygrometers usually keep data logs in their respective apps, and this guarantees that you will have up to two years worth of information at your fingertips. Additionally, you can export a spreadsheet of the data, which you can store on your computer or print out.

7. User Interface and Interconnectivity

With the advancement in Wifi, Bluetooth, and smart technology, there are many options available to connect a hygrometer to your technology. Still, many of these hygrometers come with apps that allow you to monitor your humidity levels through Bluetooth on your smartphone. However, note that not all apps have equal function and usability, so you will need to check how usable a hygrometer is before making your purchase.

8. Types of Hygrometers

There are four popular hygrometer types, and they include:

a). Electrical Hygrometers

These are the most used, and these electrical devices measure humidity changes in electrical resistance across a sensor or a semiconductor which is usually caused by the air’s moisture. Most electric hygrometers use batteries for power, and some have Bluetooth that allows you to check your humidity and temperature readings from your smartphone.

b). Mechanical Hygrometers

These mechanical types use organic materials such as human hair or ox gut to control a needle pointing to a humidity scale. When the moisture amount rises, the organic material will absorb the moisture and become heavy, raising the needle. These hygrometers work well both indoors and outdoors.

c). Dew Point Hygrometers

Dew Point Hygrometers feature polished metal mirrors where moisture condenses, but these devices need extreme conditions to monitor humidity and provide accurate readings. They use more of the old school technology and arent used as much anymore.

d). Psychrometers

Psychrometers are not common in greenhouses or kitchens, and they are more common for use in wild firefighting and for detecting danger and the potential for a fire.
