Oasis Ukulele Humidifier (OH-18)

You probably already know that your instrument can crack in dry weather. Repairing a cracked top of a fine instrument is both expensive and can alter its sound. To solve this problem our repair shop recommends the Oasis humidifiers.

The Oasis ukulele humidifier – OH-18 -is the same size as the OH-1 humidifier for guitar, but has a special hanger which allows the humidifier to hang at an angle from the strings inside the ukulele soundhole. Because the ukulele is a smaller instrument, it needs less supplemental humidification than a guitar. The humidity reduction was accomplished by modifying the liner for the OH-18 ukulele humidifier.

Made From Specially Designed Fabric

The body of the OH-18 Ukulele Humidifier is made from a specially designed fabric that allows water vapor (but not water) to pass through it. As the vapor transmission takes place, a vacuum is created and Oasis shrinks to compensate for the loss of water. By watching the Oasis humidifier shrink, you can determine when it is ready for refill. When refilling, you don’t have to guess when it is full. Simply unscrew the black cap, fill with water to the top of the container and replace the cap. Once sealed, the watertight container is your first line of defense against leaks.

Humigel, the super absorbent polymer crystals inside the Oasis Humidifier, are your second line of defense. Humigel captures up to 500 times its weight in water in an absorbent gel matrix.

Like other soundhole humidifiers, Oasis fits between the strings of your instrument. The materials that touch your strings are relatively soft and will not scratch your strings. A blue polyurethane stabilizing bar fits over the neck of the ukulele humidifier. Once positioned in the sound hole, the stabilizing bar lies across the guitar strings to ensure even weight distribution. Oasis never touches the body of your ukulele.

The OH-18 Oasis ukulele humidifier comes with the special ukulele stabilizer and a 10 cc syringe for increased distilled water filling control.

Note: Because tap and bottled water have dissolved minerals that can clog the liner, distilled water is recommended to extend the useful life of your humidifier.
