11 Best Hygrometer for Humidor and Hygrometer Calibration Kit: The Key to Perfect Flavor of Cigar

A humidor hygrometer is a mechanical instrument that is used for measuring the amount of humidity in a humidor. They come in all shapes and sizes—and some of the big cigar manufacturers have massive humidors in their facilities—but for your personal cigar humidor, you probably just need a small one. In any case, it needs to be small enough to fit inside your humidor.

The importance of Humidity:

Have you ever thought about why the best cigars always seem to come from the Caribbean and other tropical island locations? Sure, part of it is the quality and the curing of the tobacco, and the rolling also has something do with it, but as every cigar aficionado knows, cigars need humidity to have any quality at all. Places like Cuba make ideal locales for cigar manufacturing because they already have humidity in abundance. If you’ve ever been to these locations, you can probably attest to that. All you have to do is walk outside with a humidor hygrometer in one of these areas, and the readings will go through the roof.

No one’s sure why it is that cigars need humidity to keep their quality, but it probably has something to do with how the humidity keeps the tobacco’s flavorful compounds intact and also causes it to burn cooler and more slowly. The moisture in the leaves helps produce smoke that is full and tasty.

What a humidor hygrometer does

When you have a humidor hygrometer in your cigar storage humidor, it helps make sure that your cigars keep those tropical conditions that make them taste and smell so great. Shopping for one is easy. In fact, most cigar humidors made these days come with built-in humidor hygrometers, so you may not even have to worry about it. But if you have a homemade cigar case or use a container that has special meaning, then it obviously won’t have a built-in humidity measuring device.

Fortunately, buying a humidor hygrometer is easy. You can get some good ones on-line either directly from manufacturers or through large marketplace websites. Find one that is small and simple. Stay away from those complicated humidor hygrometers that are made for larger, more industrial uses. That’s just more than you need. Find a simple one, and use it to make sure your humidor stays at a level of about 68 to 74% relative humidity.

Analog or digital hygrometer?

You will find in the market analog and digital hygrometers. Analog hygrometers (like the one in the picture above) are commonly made with a metal spring, but some are made with natural or synthetic hair.

Digital hygrometers (like the one above in this paragraph) take a few seconds to show changes in humidity level, but they are easier to read and do not require calibration. This does not mean that they are 100% accurate, so you still need to check the calibration of your hygrometer whether it is analog or digital.

In general, humidors use analog hygrometers.

Humidor with analog hygrometer

There are three systems of analog hygrometers:

Spiral analog hygrometers:

Spiral analog hygrometers are used in the majority of humidors. They are less expensive but they have a limited accuracy.

Analog natural hair hygrometers:

This type of hygrometers is more accurate. However, they require a lot of maintenance work for maintaining their accuracy. For this reason, they are not the first option to use in humidors.

Analog synthetic hair hygrometers:

This hygrometer has a similar accuracy to that of the natural hair, but they do not require maintenance on the part of the costumer. They are the most used in humidors. Analog Hygrometer by Western Humidor are made up with high-quality synthetic hair. They are manufactured by a Cigar Oasis, in a special cigar edition that has been improved to measure with accuracy the high humidity levels in humidors. These hygrometers are highly accurate within a short interval of humidity, whereas, normal hygrometers achieve highest accuracy at a lower level of humidity, between 30 and 60 %.

For the typical levels of humidity over 65% in cigar storage, the accuracy of analog and digital hygrometers significantly decreases. The disadvantage of analog hygrometer is that you need to more care to maintain it and you need calibrate the hygrometer to use it first time. Another alternative is to equip the humidor with a digital hygrometer which is more accurate.
Digital hygrometers are easier to read and they do not require calibration. It is important to highlight that digital hygrometers need a very short period to adapt to changes in humidity that means immediately. Likewise, they are more accurate than the analog hygrometers. Another advantage of digital hygrometer is that some digital hygrometer also read the temperature.

Humidor with digital hygrometer

However, the Caliber IV Digital Hygromter by Western Humidor is one of the few digital hygrometers on the market that has been optimized to achieve the best accuracy at humidity levels over 65%. You can also check HygroSet II Digital Hygrometer by Quality Importers.
There is another option for you is that the combo of analog and digital hygrometer be Western Humidor. Analog or digital, its totally depend on your passion but in case of accuracy digital hygrometer is best.
