Boveda Hygrometer calibration Kit

Hygrometer calibration is one of the most important parts of caring and preserving your tobacco. How would you know if your product is at the appropriate RH level if your hygrometer isn't working correctly?

Ensure that your hygrometer is at the correct RH level with Boveda's One-Step Calibration Kit. Watch our instructional video to learn more.

Boveda’s two-way humidity control technology—as used in the One-Step Calibration Kit—is based on scientific principles (Raoult’s Law and Henry’s Law) that have been known for well over 100 years. One of those principles is that a saturated solution of salt in water will maintain a constant level of relative humidity inside an enclosed chamber. This immutable law is the foundation of Boveda. This principle is widely used and accepted by chemists and lab professionals to determine the accuracy of any hygrometer, whether digital or analog. This is why Boveda should be used to establish the correct level of humidity inside your container, package or humidor, or to check the accuracy of your hygrometer.

Note: Do not mix Boveda RH levels within the same humidor, and do not use Boveda in the same humidor with other humidification products. They will fight against each other and reduce the efficiency of the Boveda. 

• Exterior Bag Dimensions: 5.5" x 7"
• Interior Bag Dimensions: Approx 4" x 4.5"
• 75% remains at 4 yrs if left unopened.

Instructions: 

• Simply place your hygrometer inside the bag and completely re-close the zipper.
• Allow the Calibration Kit to sit for a minimum of 24 hours at room temperature, 65 to 75°F
• The hygrometer should read the RH% level stated on the Calibration Kit. If Not, note the difference for the future readings or adjust* your hygrometer if applicable.
