Boveda One-Step Hygrometer Calibration Kit

The One-Step Calibration Kit is a simple and surefire method to accurately calibrate any digital or analog hygrometer or humidity sensor.

The One-Step Calibration Kit utilizes Boveda’s 75.5% relative humidity standard, which is widely used and accepted by chemists and lab professionals to determine the accuracy of any hygrometer (also known as the “salt test”).

Simply place your hygrometer inside the bag, close the zipper, and wait 24 hours.

A perfectly-calibrated hygrometer will read 75% Rh.

If your hygrometer reads above or below 75%, adjust the calibration by the number of percentage points it is off from 75%.

- Inaccurate hygrometer readings put premium cigars at risk. Precisely calibrate digital and analog hygrometer and humidity sensors, so they give accurate relative humidity (RH) readings of what’s going on inside a humidor.

- Easy, mess-free calibration—Simply place a hygrometer or humidity sensor in the airtight high-density bag with the enclosed Boveda humidity pack. Zip closed and check back in 24 hours.

- Reusable—Good for 3 months after opening (2 years if unopened in original packaging). Re-calibrate a hygrometer or humidity sensor every 6 months to keep it performing effectively.

- 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.
