This is one of the most important parts of caring and preserving your cigars. Ensuring that your cigars are at the appropriate RH level is of utmost importance.
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 check the accuracy of your sensor.
The One-Step Calibration Kit utilizes Boveda's 75% or 32% relative humidity standard. Simply place your sensor inside the bag and close the zipper. Allow the Calibration Kit to sit for a minimum of 24 hours at room temperature, 65 to 80°F. A perfectly calibrated sensor will read 75% or 32% RH (depending on the calibration kit you are using). If your sensor reads above or below that number, the App will adjust the calibration value by the number of percentage points it is off from 75% or 32%, commonly called the offset.
For even more accuracy, you can use both RH levels and perform a two-point calibration. Perform the calibration steps in one bag, then move the sensor to the other bag and perform another calibration.
The Boveda One-Step Calibration Kit is guaranteed to be accurate for up to 3 months after opening. We recommend calibrating the Boveda Smart Sensor every 12 months.
Once the calibration has started in the App, you can close the App and even exit Bluetooth range. The Boveda Smart Sensor and App will continue to measure data and calibrate your sensor.
