Simple and Clear

However, most cigar enthusiasts are not interested in performing an almost-scientific analysis every time they need to check their humidor’s moisture. For that reason, products such as the HygroSet II Round Digital Hygrometer for Humidors emphasize simplicity, readability, and overall straightforwardness.

Compared to the Caliber IV Digital Hygrometer by Western Humidor and, frankly, most other hygrometers on the market, this product is minimal and simple in its design.

This efficient and reliable device is so small that it can fit in basically any nook or cranny in a humidor. Largely, this ability to be placed anywhere has to do with its slim profile and round shape. These two characteristics provide a great economy in volume without sacrificing functionality, ergonomics, readability, or overall quality.

What Should You Know Before Buying?

Going a bit further regarding the simplicity and efficiency of this product’s design, it can be mentioned that, despite being very straightforward, its display is very intuitive and easy to understand. Additionally, it is quite large, particularly considering the compact size of the device itself. As a result, it can be used without problems by people that have visual difficulties when it comes to reading small displays.

What Else?

Not only that, but the HygroSet II Round Digital Hygrometer for Humidors can be operated and calibrated with only a few pushes of its three multi-function buttons.

Even though this may seem like a daunting task at first, after reading the instructions included with the purchase of this product, you will be an expert.

At this point, it would probably be important to mention that many of the comments about this product featured on review sites marveled about its affordability.

Despite being between five and ten dollars cheaper than most other high-quality products of its kind, however, the HygroSet II Round Digital Hygrometer for Humidors had earned excellent reviews by both customers and specialized critics, including experienced cigar enthusiasts.

Verdict

The Feature You Would Appreciate

While the product’s display is not the most visually-alluring available on the market, its color-coded design makes it both intuitive and easy to understand, allowing first-time users to begin monitoring the humidity in their humidor as soon as the product comes out of the box.

As if this wasn’t enough on its own, the Caliber 4R Gold Digital/Analog Hygrometer features a gold antique compass-styled look that makes it, by far, the most visually-alluring product on this list.

Like most products of its kind, this device offers both temperature and humidity readings that can be switched between Celsius and Fahrenheit with the push of a single button. Apart from providing a precise +/- 1% level of accuracy at all times, the Caliber 4R Gold Digital/Analog Hygrometer provides other pieces of data that may be crucially important for advanced cigar enthusiasts to precisely monitor the levels of humidity in their humidors.

Best Price, Best Design

Without a doubt, one of the most important is the three-day high/low/average data display because it provides important information regarding humidity levels over extended periods.

It should be mentioned that most of the complaints directed at this product will have to do with its subpar display. Featuring dimensions of 2.7 x 2.6 x 1 inches, this is, by no means, a large device.

While this characteristic may be beneficial in many ways, it does not pair well with the low resolution and underwhelming brightness of this product’s display.

Due to these two aspects, the display is tough to read in certain conditions. With full disclosure in mind, it can even be said without exaggeration that reading this display at an angle can be problematic. Unfortunately, trying to read it under broad daylight is also out of the question.

Verdict

Despite its most visible faults, the Caliber 4R Gold Digital/Analog Hygrometer is a complete, efficient, and reliable piece of technology that will undoubtedly help you keep your cigars in their best shape. Stable, durable, and easy to calibrate, it is certainly a reliable device.

Best Hygrometer For Humidor – Buyer’s Guide

What is a Hygrometer?

Simply put, a hygrometer is a device that measures the level of humidity (moisture) that is in the air at any given time and place.

This kind of device can be used for various specific purposes in mind or simply to monitor humidity in a room (for example, a hospital waiting room).

However, for this buyer’s guide, we will discuss digital hygrometers in terms of their use for humidors.

At this point, it should be mentioned that, typically, digital hygrometers are used in combination with one other device: A humidification device. Employing both these devices, a cigar aficionado can ensure that its cigar collection will remain fresh and delicious for extended periods.

One of the most important things to understand about a hygrometer is that it only monitors temperature and humidity levels in a certain area.

That means that a digital hygrometer for a humidor cannot regulate temperature or humidity by itself. However, it does provide a reliable and immediate reading of these factors that can help users correct and adjust the environment to have the perfect conditions for maintaining cigars fresh and flavorful.

What is a Cigar Humidor?

When asked about keeping cigars fresh, most people imagine the classic wooden box setup popularized in movies and pop culture in general. However, the old-school wooden box may be one of the best ways to ensure your cigars will become stale and dry in no time. The truly knowledgeable way to maintain your cigar collection fresh, on the other hand, is a cigar humidor.

A cigar humidor is a storage container designed to maintain a certain humidity level despite external conditions such as the weather. Simultaneously, cigar humidors help maintain the temperature within a certain range to prevent problems such as mold or frostbite.

Cigar humidors are vital for keeping cigars fresh and moist. This is important because the tobacco leaves that make up a cigar can contract and expand depending on the humidity level in the air around them.

Apart from varying in size, cigars that gain or lose too much moisture will be subject to various changes in their physical integrity. Logically, these changes will result in variations in flavor, aroma, burning abilities, and overall quality.

Without a doubt, however, the biggest problem that comes with variations in the physical attributes of a cigar is its drying up. When tobacco leaves dry up, they become shriveled and lose a good amount of their characteristic aroma and flavor.

As if that was not bad enough, dried up tobacco leaves will burn too hot and quickly, making the cigar difficult to smoke properly.

On the other hand, cigars that are too moist can be difficult to burn and smoke. Additionally, too much moisture can lead to problems such as mold and rot. However, that is not all, as these problems can also attract a dangerous species of beetle known as the tobacco beetle.

Because of their voracious disposition, once these animals get in your cigar collection, you can say goodbye to them.

What are the Additional Uses of a Hygrometer?

  • Hygrometers aren’t limited to monitoring the humidity of a cigar humidor. To be sure, digital hygrometers can be used for a variety of purposes, including:
  • Controlling humidity in a room for medical reasons.
  • Minimizing humidity to control mold growth.
  • Reducing the danger of viruses, bacteria, dust mites, fungi, and other asthma-inducing agents appearing.
  • Creating an apt environment for indoor plants to grow healthily.
  • Protecting expensive equipment from being ruined by excessive humidity.

Digital vs. Analog Hygrometers

Essentially, there are two types of hygrometers: digital and analog. Analog hygrometers are the most ubiquitous. These hygrometers typically use arrows that move and point to a certain number in a wheel to designate the metrics.

Very often, humidor containers will include an analog hygrometer as a part of their setup. For that reason, it may be tempting to trust them. However, it should be remarked that analog hygrometers tend to be a lot less accurate than their digital counterparts.

As if that was not bad enough, analog hygrometers are very difficult to calibrate properly. For that reason, many cigar experts completely disregard their use, choosing instead to trust a digital hygrometer such as the ones featured in this guide.

How Can You Calibrate Your Hygrometer?

To make sure that the humidity and temperature readings provided by your hygrometer are accurate, you need to calibrate the device with a certain level of regularity. To do this, you need to purchase a calibration kit.

Once you have this device, place your hygrometer in a Ziploc bag. Next, seal the bag and place it in a dry and dark place. After 24 hours, please take out the hygrometer and compare its reading to the calibration kit. If there is a difference, adjust the hygrometer to match the calibration kit.

What is the Best Humidity and Temperature for Keeping Cigars Fresh?

Without a doubt, there is a great deal of controversy regarding the best humidity for keeping cigars fresh. Even though many experts have very definite opinions regarding this subject, there is no consensus among them. In the end, it all comes down to personal taste.

However, typically, cigar vendors and enthusiasts recommend getting as close as 70 RH% per measure. When it comes to Cuban cigars, though, many of the same experts will recommend going down as far as 65 percent. Regarding temperature, typically, it is advised to get the humidor going at around 70 degrees Fahrenheit. This, too, however, depends largely on personal taste.

Frequently Asked Questions

What is the most accurate way to measure humidity?

I believe that only digital hygrometer can give you the right measurement of humidity. So, don't be shy and buy only digital 😉

Are digital hygrometers accurate?

Yes, because manufactures like Cigar Oasis use modern technologies to make only best product on the market.

Do digital hygrometers need to be calibrated?

No, they were calibrated on the factory, but you can use salt method to understand the margin of error of your instrument.

How do I know if my hydrometer is accurate?

My recommendation - watch the video below (yes, you can use this method for any hygrometer)

How Long Can You Keep a Cigar Without a Humidor?

Typically, a cigar will not last very long unless it is stored in a humidor. However, the amount of time that it will remain fresh can be stretched slightly by putting the cigars in a sealed Ziploc bag. As an additional measure, you may place the Ziploc bag inside a Tupperware container, which will give you some extra hours. At any rate, if you do not have a humidor, you should get one as soon as possible. Until then, however, try to smoke your cigars within the first two or three days of buying them.

Can You Revive a Dry Cigar?

To a certain extent, yes. Cigars can be re-humidified by being placed in a humidor for a certain time. Typically, this period ranges between one week and three weeks. Largely, the amount of time needed for a cigar to be revived depends on both its thickness and how dry it is. At this point, it is important to note that you should never increase the humidity in your humidor, hoping to speed up the re-humidification process. If you do this, the violence of the process will likely end up tearing holes in the cigar's wrappers.

What is Dry Boxing and How Can You Do It?

Put, dry boxing is the act of putting a cigar in a wooden box for a few hours before smoking it. The reason is that it eliminates the probability of the cigar burning incorrectly due to being plugged. It should be pointed out, however, that this is not an issue that all cigars have. All cigars are different, and, as a result, they need to be treated in a particular way.

Should You Take the Wrapper Off Cigars Before Putting Them in a Humidor?

Again, this is a matter of preference. However, it should be noted that most cigars are wrapped in cellophane, a porous material that allows them to breathe and maintain their humidity. For that reason, many cigar experts vote against taking the wrapper off of cigars before putting them in a humidor.

In Conclusion

Hopefully, having gone through this guide, you have a clearer understanding of what a digital hygrometer can do for you and your cigar collection. At any rate, you will be able to compare some of the best digital hygrometer products on the market, making it easier to choose the best one for you.
