OH-5
While the original Blue Oasis® provides sufficient humidity in many environments, it is not effective everywhere. The humidity demands of the desert, mountain states or frigid north exceed the humidification capacity of the OH-1. For this reason, we have developed the OH-5 Plus+ humidifier. The OH-5 Plus+ is the same size and shape as the original blue Oasis®, but is has a different liner which provides 50% more humidity output. Because the OH-5 Plus+ is the same size as the original Blue Oasis® and it has 50% greater humidity output, it will be necessary to refill the Oasis® OH-5 Plus+ more frequently than the original Blue Oasis®. Use the OH-5 when the environment outside the case has a relative humidity of 25% or less. Each OH-5 comes with a stabilizer bar for mounting the OH-5 humidifier and a 10 cc syringe for distilled water filling control.
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.
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.
