Description

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 32% 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 32% RH. If your hygrometer reads above or below that number, adjust the calibration by the number of percentage points it is off from 32%. Then place the hygrometer back in the bag to check that the adjustment worked.

Interior Bag Dimensions are approximately 4" x 4.5". Lasts approximately one year after opening. 4 year shelf life before opening. TW# 80923
