Best Hygrometers: Monitor Changes in Temperature and Humidity

Climate can be affected by numerous factors, one of which is none other than humidity. Most tropical regions of the world are affected by a high concentration of humidity in the air. And it severely impacts the daily lives of people who live in these regions. Even if you do not live in a severely humid region like the tropics, there are some products that require special care. Humidity can cripple the quality of the product, in such cases, one of these best hygrometers can help you out.

What most people don’t know, humidity is not a very human-friendly condition. It can become hard to breathe and you tend to sweat way more which can cause dehydration. Also, humidity promotes some unfriendly conditions in your living environment. It promotes the growth of bacteria and fungus, which is harmful to the human body. We need to avoid such living conditions at any cost, as it can risk disease.

There are products like dehumidifiers for keeping our living environment healthy. But as we said some products decline in quality under humid conditions. We need to constantly monitor them and ensure that humidity levels are down. Even if you place these items in a humidor even then hygrometers are used to monitor the situation of humidity inside of them.

Uses of a Hygrometer

The most common use of hygrometers is in small enclosures or humidors in which you can store items. To protect items from humidity, you place them in humidors. One such example of such items, in fact, a very common example would be cigars. Cigars are very susceptible to humidity, they can mold and lose their quality very quickly if they are not stored properly in humidors. It would be a waste of money since cigars are a very expensive item.

To see that the humidity levels inside a humidor are bearable, a hygrometer can be placed inside of it. If the humidity levels are not ideal, you can do something to improve the conditions. But knowing the levels is important. People also use hygrometers inside reptile tanks or terrariums. Because these creatures require certain living conditions, it is important to ensure the levels are stable and not too high or low.

Hygrometers are very useful tools, to know how to find the ones, let us look at a detailed buyer’s guide.

Buyer’s Guide on Choosing the Best Hygrometers

There are many types of Hygrometers available in the market. To choose the best hygrometers for your needs, you need to know what they will be used for and the types of hygrometers in the market. Knowing both of these things will help in the selection of the one that you will need for yourself. Let us explore in further detail below.

Cigar Humidors

As we said earlier, one of the most common cases used for hygrometers is cigar humidors. A humidor is a case that seals off moisture. So the item placed inside it stays safe from excess levels of humidity. Cigar enthusiasts and sellers often stock up on these, and they can be extremely expensive. A box of Cuban cigars, one of the best in the world, can go for anywhere around $300 or more depending on the brand. Vintage cigars can cost even more. Their prices sometimes exceed $1000 in the market.

Only a cigar enthusiast will go ahead and spend that much amount on them. But if you do not keep them away from moisture, you cannot store them for a long time. Expensive cigars come in humidors already, placing a hygrometer inside of it can be beneficial. It will be an assurance to know that your expensive indulgence is not going to lose quality. These vintage cigars are treated at very low moisture levels to give them their taste and quality. They lose taste and texture if they are exposed to high moisture levels again.


Reptiles are very sensitive creatures and require warm and humid habitats to survive. If the moisture levels are not maintained, their skin starts to shed prematurely. This is hazardous to their health. If you are a reptile enthusiast and have lizards or snakes, you will have to keep an eye on the moisture level inside it. With the help of a hygrometer, you can keep your reptile in suitable environments. Without it, however, you might risk the health of your reptile.

Placing a hygrometer inside of the reptile tank or terrarium will tell you what is the moisture level in it. You can put a small humidifier in the tank at intervals to improve the humidity inside it.

Medical Reasons

Due to excess humidity fungus, bacteria, mold can grow really fast. You will find mold growing on walls with ingress and you will also see fungal growth as well. These can be harmful to a person’s health normally. It is specifically harmful to those with conditions related to their breathing like asthma. If you are a patient of any breathing disease, you would want to ensure that there isn’t any fungal or bacterial growth in your living premises.

To make sure that the growth of such harmful things is not possible in your home, you need to have a hygrometer to monitor the moisture in the air. If you keep an eye on the humidity levels, you can use a dehumidifier when required.

Protecting Expensive Equipment

Oxidation is a chemical reaction in which elements gain oxygen. If you are not very familiar with the term itself, rust is a great example of oxidation. You know how harmful rust can be to uncoated steel equipment. Even if the element has rust immune tendencies, oxidation can still harm it. An example of this is how silverware if not maintained slowly turns dark in color. If you want to protect expensive equipment like silverware, placing a hygrometer will do you good. It will notify you if there is a lot of unneeded moisture in the air.

Digital and Analog Hygrometers

If you are looking at the types of hygrometers available in the market, you will find either a digital or an analog hygrometer. Many cigar humidors have an analog hygrometer in them already when you purchase them. Cigar enthusiasts prefer the aesthetics of an analog hygrometer. It looks like a watch or compass with needles and a metal frame. But in reality, it is just good in aesthetics as it is less accurate compared to a digital hygrometer.

If you need accurate numbers, we would suggest you look at a digital one. The digital hygrometer sometimes also helps in pointing out the temperature of an enclosure. Analog hygrometers are still made in the same ways as they were in older days.

Now let us look at some of the best hygrometers in the market:
