Take the guesswork out of protecting your instrument. When the relative humidity drops below 40%, a guitar, or any wooden musical instrument, is at risk of cracking or warping. The Oasis OH-2 Digital Hygrometer accurately measures relative humidity, helping you decide when to protect your instrument with the Oasis Guitar Humidifier (sold separately). Because relative humidity varies even inside your home, it is recommended that you keep your hygrometer near your instrument.
