Each Le Veil humidifier is equipped with a high-quality capacitive humidity sensor; the same used in commercial laboratories. Most digital hygrometers available to the public are equipped with resistive hygrometers which have an RH variance of up to +-10%. Please make sure the hygrometer you are using to test the humidifier has a capacitive humidity sensor to ensure accuracy.
The Le Veil humidifier allows you to manually adjust and re-calibrate its hygrometer using the steps below. After adjusting, place the humidifier back into the humidor and allow 24 hours for accuracy.
