What is a hygrometer?

Complex name for a simple but useful device.

A hygrometer is an electronic device that tells you the current humidity level. It essentially tells you how much percentage of moisture is in the air. So, if the reading on the device is 65%, that means the air is 65% saturated with moisture. 

Hygrometers help users keep an eye on humidity levels so they can take steps to reduce it if it exceeds the level they want. Homes in humid climates, museums, and saunas commonly use the device. All of which are locations where you would want to keep tabs on air moisture. 

Why do you need a hygrometer for a humidor?

If you’ve ever owned a humidor, you know the importance of maintaining humidity. Cigars need a certain amount of moisture to hold their taste. Otherwise, the tobacco leaves inside will dry out, resulting in the loss of aroma and flavor. 

A hygrometer paired with a humidor lets you keep track of moisture levels. So, you know when you need to adjust it to ensure the cigars hold flavor and aroma. The device is an investment for cigar lovers.

We recommend this device for beginners and experts both. It comes calibrated, and ready for use. So you just need to turn it on and stick it inside the box. After some time though, you will need to recalibrate it. The process is fairly easy, but we recommend you use a Boveda calibration kit.

The only downfall of the device is its dimensions. It is 4 inches (10.16 centimeters or cm) by 1 inch (2.54 cm) by 6 inches (15.24 cm). So, not suitable for smaller humidors. Overall, the device has tons of useful features that will help you track moisture in a humidor.

The device is also sturdy and stylish in part because it features a gold trim. It is also very accurate in providing you with moisture level readings. It comes with a magnet attachment, which is a bit small. In the event that the magnet isn’t working out, velcro will help the hygrometer to stick to the humidor. Overall, the design and capability of the device make it a great choice.
