Hygrometer humidor is used to measure the relative humidity. It is widely used by the cigar smokers to preserve and age cigars in a constant humidity level. To measure the humidity level hygrometer is used. Some types of humidors come without hygrometer. In them, you should buy a hygrometer separately and attach it with the humidor. But in hygrometer humidor, hygrometer is attached to the humidor itself.
Analog hygrometer comes with a metal spring or natural hair or with synthetic hair. Most of the hygrometer humidor makes use of metal spring. This hygrometer humidor is less expensive but the accuracy level is also limited. Hygrometer humidor using natural hair is more accurate. But the maintenance work needed is substantial. So, even this is not preferred. Hygrometer humidor making use of synthetic hair gives results as accurate as the one using natural hair. But it does not require any maintenance on its part. So, this is what is used in most of the hygrometers.
Digital hygrometer humidors are very famous these days. Internal temperature stabilization is very easy with digital hygrometer humidor. It makes use of digital thermometer. This helps you to find out the relative humidity, area temperature as well as the temperature of the atmosphere. So, correct humidity level could be easily measured using digital hygrometer. The different types of digital hygrometers are digital thermo hygrometer, digital hygrometer humidor, digital thermometer hygrometer, digital cigar hydrometer, etc. Digital hygrometer humidor is preferred for such reasons as this does not require calibration and this has easier readability of the measurements. But this does not mean that digital hygrometers are more accurate than analog ones.
The hygrometer humidor warns you against the fluctuations in the level of humidity found and provides the right environmental conditions to preserve your cigars kept inside it. Hygrometers need initial adjustment for accurate results. You have to calibrate them. If the humidity level of your room ranges between 30% and 60%, you want to keep the level of hygrometer humidor over 65% levels. Only then it will retain the original flavor and taste. If the hygrometer shows less moisture level, then you may need to dampen your humidifier by pouring distilled water. In this way, you could maintain the required level of humidity.
