Without proper calibration, a hygrometer's readings are merely guesswork. And guessing bout RH puts moisture-sensitive products at risk. 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. Boveda's Calibration Kit ensures a consistently accurate reading by adding and removing pure water vapor to achieve and maintain 75% RH in the controlled environment of the Calibration Bag.
How Does the Boveda One-Step Calibration Kit Work?
Simply place your hygrometer or humidity sensor inside the bag
Close the zipper and wait 24 hours
Check the reading, a perfectly calibrated hygrometer will read 75% RH
If the reading is above or below 75% RH, adjust the hygrometer by the number of percentage points it's off
Place the hygrometer back in the bag and zip it closed to verify that the adjustment worked
For ever more accuracy, run a two-point calibration using both of Boveda's Calibration Kits
