ONE WORD: CALIBRATION. The Boveda Butler is the only humidor monitor for cannabis containers equipped with the Boveda One-Step Calibration Kit. The only way to ensure curing and long-term storage readings are truly accurate is with a well-calibrated Boveda Butler.
Chemists and lab professionals determine the accuracy of a hygrometer with a “salt test.” The Boveda One-Step Calibration Kit is the ultimate salt test.
In just 24 hours, you can perfectly calibrate the Boveda Butler’s digital hygrometer. For even more accuracy, check readings at the lower end of the RH level spectrum. Run a two-point calibration using a Boveda One-Step Calibration Kit 32% RH (available separately).
