The Oasis Hygrometer Holder was created to allow the user to measure humidity at the body of the guitar without the risk of scratching the soundboard. Made from a soft loop Velcro type material, it wraps around the 1st string and provides a flat surface where the hygrometer can be attached. An adhesive backed piece of hooked Velcro type material is attached to the back of the hygrometer.

Guitar cases are designed with a cradle to support the neck of the guitar. This is also where the supply/accessory box is located. This area creates a humidity barrier. A humidifier located at the headstock will humidify the head and neck, but not the guitar body. A humidifier placed in the soundhole will humidify the body of the guitar but not the headstock. Placing a hygrometer either at the supply box or the headstock will not give accurate humidity measurements when the humidifier is located in the soundhole. Accurate humidity measurement is possible when the hygrometer is positioned near the area where the humidifier is located.
