Western Humidor's Caliber hygrometer was the first digital hygrometer designed for your cigar humidor. It was an immediate hit thanks to its slim design and accuracy, and over the years we sold thousands of these units. Now, Cigar Oasis and Western Humidor have teamed up, the Caliber III has been discontinued, and the new Western Caliber IV digital hygrometer has arrived. The new Caliber IV has kept the same accuracy and slim profile as its predecesor but with one very convenient added feature: adjustable calibration. With the push of a button you will now be able to adjust the display setting.
