Other gauges measure the humidity in the air that surrounds the cigar, which can be markedly different than the actual humidity reading in your cigar.
It is widely assumed that the humidity (or moisture content) within the cigar replicates the humidity level in your humidor. This is not always true. It can take weeks and sometimes months for a cigar to reach equilibrium.* The HumidiMeter™ will inform you instantly how close to equilibrium your cigar really is.
* Humidity in a cigar and humidity in the humidor in which the cigar was stored are equal
