OH-14
The OH-14 Case Plus+ Humidifier uses the same evaporative membrane as the OH-5 Plus+ Humidifier, providing 50% more daily humidity than either the OH-6 Case Humidifier or the OH-1 Guitar Humidifier. This humidifier is designed for use in drier climates (desert, mountain or frigid north) where the relative humidity is below 25%. The OH-14 Case Plus+ Humidifier, like the OH-6 Case Humidifier, attaches to the inside of your instrument case. To accomplish this, two powerful neodymium magnets are inserted in the seam of the humidifier. The magnets attach to either a steel clip or a stainless steel strip with adhesive backing (both are provided with the humidifier). The steel clip fits over the side of your case, providing a flat vertical surface to which the magnets can adhere. The neodymium magnets are strong enough to keep the humidifier attached to the clip or strip, but still allow the user to remove the humidifier with ease.
The OH-14 Case Plus+ humidifier can be used to humidify the headstock of a guitar by attaching the clip over the backside of the case. The humidifier can also be used in stringed instrument cases such as violin, viola or cello by attaching the stainless steel strip to the inside of the instrument case with the double sided tape. The steel clip and strip give the user a wide variety of ways to attach the humidifier to the case. Like all of our humidifiers, we provide a 10 cc syringe for distilled water filling control.
OH-2
The OH-2+ is the latest version in the OH-2 hygrometer product line. It has a new digital sensor that im-proves the accuracy of the hygrometer to +/- 3% between 20% – 80% RH. The hygrometer also has an ex-tended reading range down to 10% RH rather the 20% RH on the previous two models. This eliminates the annoying “LL” sign one 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. If calibration is desired, you first need to get a Boveda one-step calibration kit. They come in 32 and 72% calibration levels. Place the OH-2+ in the pouch and let the hygrometer wait overnight in the bag. The humidity in the bag will be either 32 or 72%. If your hygrometer reads differently, figure out the % difference. The hygrometer can be adjusted up or down by 6%. Push the upper set button and hold for 5 seconds until is starts blinking. Push the min/max button repeatedly. The % change will start at 0 and move up to 6. If you keep pushing, the next number will be -6% and it will go down to 0 by continuing to push the min/max button. Whatever you calculated was the percentage difference between -6 and +6% is shown on the screen. Press the set button and the display returns to normal but is adjusted for the difference you entered in the processor.
Don’t forget the OH-20 hygrometer holder that allows you to place the hygrometer near the sound hole for accurate RH readings.
