If you're a cigar aficionado, you need a hygrometer to make sure you're storing your wares at the correct humidity. A hygrometer is an instrument that is used to measure humidity in cigar humidors as well as greenhouses, incubators, museums, and more. To ensure that your hygrometer is functioning properly, it is best to test it prior to use, then calibrate it if necessary. The salt method is a tried and true way of testing a hygrometer for accuracy. Here's how to do it. | If you're a cigar aficionado, you need a hygrometer to make sure you're storing your wares at the correct humidity.
