Oasis® OH-2 Digital Hygrometer
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. Because relative humidity varies even inside your home, we recommend that you keep your hygrometer near your instrument. For safe placement next to a guitar soundhole, see the Oasis® OH-20 Hygrometer Holder.
