The easiest instructions you’ll ever read.
The Boveda hygrometer calibration kit consists of two parts: A high strength bag and a 75.% Boveda inside. Simply place your hygrometer inside the sealed bag and in 24 hours you’ll know the accuracy of your hygrometer, and you can adjust accordingly. Our calibration kit is used by various industries to test the accuracy of their sophisticated equipment because it saves the mess and hassle of the traditional “salt and water” test.
