ONE-STEP CALIBRATION KIT

Description

Humidity meters are imprecise instruments that require calibration every 90 days. They typically lose their calibration over time and after battery replacement. The 100% accurate way to calibrate your hygrometer is with the Boveda Calibration Kit. Each kit includes a bag and a Boveda 75.5% packet. After 24 hours in the bag, you’ll know the accuracy of your hygrometer. Each kit lasts about a year and is reusable.
