HULECOS: The first technology that gives you your cigars’ moisture content for the best possible tasting
Relative humidity, as indicated by your hygrometer, does not reflect the actual moisture content of the air surrounding your cigars, because it varies with temperature. For example, at a relative humidity of 70%, the air contains 36% more moisture at 25 °C (77 °F) than at 20 °C (68 °F).
Cigars are hygroscopic. Hulecos developed the Cigar Moisture Content model (HMC2), which accurately reflects the moisture content of cigar leaves, regardless of temperature and relative humidity.
The H1 displays the cigar’s moisture content (HMC2) using simple symbols:


H1: The ideal assistant for optimal cigar preservation in your humidor (PRESERVATION MODE)
Equipped with its dedicated cap inside the humidor, the H1 calculates and displays the relative humidity (RH) level required to reach the desired HMC2 level, based on the current temperature. After automatically collecting the data, the H1 provides recommended adjustment settings.

- At the current temperature, what level should you set to restore the 70/70 rule?
- What level is needed to reach the maximum permissible moisture content?
H1: The ideal assistant for analyzing each cigar individually for optimal enjoyment (TASTING mode).

H1 lets you test the preservation quality of each cigar in your humidor. Compare them to make better choices and adjust your humidor settings if necessary.
H1 ensures that the cigar you are about to taste is maintained at the optimal moisture level so you can fully appreciate its flavor and enjoyment.

Cigar moisture content: a scientific challenge
Cigars have their own mechanism for interacting with water: they are hygroscopic, which means they absorb water from the air into their leaves through a unique physicochemical process, similar to a sponge.
Hulecos tested various mathematical models to determine the water concentration in cigars and established the optimal model, Hulecos Cigar Moisture Content (HMC2).
Regardless of temperature and relative humidity, HMC2 clearly reflects the actual preservation state of your cigars.
Temperature plays an important role and is always combined with relative humidity. Temperatures above 24 °C can lead to the development of ladybug eggs, with a devastating effect on your cigars.
HMC2 calculates EMC (equilibrium moisture content). The recommended EMC for cigars is generally between 12% and 15%.
Relative humidity measures water vapor pressure. It is important, but it is not sufficient on its own to determine the actual moisture content of cigars.
Hulecos Certification: a mark of distinction and excellence for cigar retailers and lounges.
By choosing HULECOS certification, your establishment becomes a recognized certified venue, demonstrating your commitment to unrivaled cigar preservation and offering your customers exceptional quality and experiences.
