Oasis Caliber V Slim Digital Hygrometer

Precision You Can Trust A Must-Have for Serious Cigar Storage

I recently added multiple Cigar Oasis Caliber V Slim hygrometers to my tower humidor, and they’ve completely elevated how I monitor and manage my collection. What stands out immediately is the consistency. After proper calibration, I placed units across different levels — bottom, drawers, and top shelves — and the readings have remained incredibly stable, with only a natural 1–2% variation throughout the humidor. That level of accuracy gave me full confidence that my environment is truly dialed in. I maintain my humidor at 68% RH, and these hygrometers have been instrumental in confirming that stability without constantly needing to adjust my system. They respond well, settle quickly after opening the door, and provide clear, easy-to-read data at a glance. The slim design is another big advantage. They fit perfectly inside drawers and on shelves without interfering with airflow or storage space, which is crucial in a fully loaded humidor. If you care about precision, consistency, and protecting your cigars properly, the Caliber V Slim is an essential tool. It takes the guesswork out and replaces it with confidence. Highly recommended.

Amazing product

The western caliber v is by far the best hygrometer I’ve used to date for my cigars. I had the older caliber 4 and 4 round. These are really accurate out of the box. I bought 4 of these, 2 were dead on after 36 hours in the calibration bag and the other 2 were off by 1%. Not a big deal seeing how you can calibrate them with a push of a button. I love the new screen, so easy to read in any light.

Great add to my humidor
