When the relative humidity drops below 40%, a guitar, or any stringed musical instrument made of wood, is at risk of cracking or warping. The Oasis? Digital Hygrometer accurately measures relative humidity, helping you decide when to protect your instrument with the Oasis? Guitar Humidifier. Because relative humidity varies so much, even inside your home, we recommend that you keep your hygrometer close to your instrument.
How does it work? To get an accurate humidity reading for the guitar body, we recommend that you first lay the guitar case with the back to the floor and open the cover. Take a small piece of cloth, and place it under the hygrometer to avoid scratching the top of your guitar. Put the hygrometer on the guitar top with the sensor at the edge of the sound hole. Close the case, and allow 4-6 hours for the humidity to stabilize. Open the case and look at the reading within a few seconds, and you get the humidity reading that existed just before you opened the case.
Because the Oasis humidifier will somewhat distort the humidity reading, take readings with the Oasis humidifier in place and take readings without the Oasis humidifier. A well-humidified guitar in its case will have relatively stable humidity readings, so you don?t have to measure the humidity all the time.
The OH-2+ is the latest version in the OH-2 hygrometer product line. It has a new digital sensor that improves the accuracy of the hygrometer to +/- 3% between 20% - 80% RH. The hygrometer also has an extended reading range down to 10% RH rather the 20% RH on the previous two models. This eliminates the annoying ?LL? sign on the display when the humidity drops below 20% RH. The increased range will help those users in extremely dry areas to get a more accurate reading of their humidity.
The humidifier has the same size and look as previous versions. The calibration feature is also included, but shouldn?t be necessary with the improved accuracy. Don?t forget the OH-20 hygrometer holder that allows you to place the hygrometer near the sound hole for accurate RH readings.
