OVERVIEW

Get the info you need to keep your guitar in prime condition.

When the relative humidity drops below 40%, musical instruments are at risk of cracking. The Oasis Digital Hygrometer accurately measures relative humidity and can help you decide when to use your Oasis Guitar Humidifier. Because relative humidity varies greatly, even inside your home, we recommend that you keep your hygrometer close to your guitar, or any other stringed musical instrument made of wood.

With the convenient case clip, it is now possible to measure the relative humidity inside your guitar case so you see when it's necessary to humidify the instrument. The clip attaches to the back of the OH-2 hygrometer and is mounted on the flap of the supply box inside your guitar case.

While, $25-$30 seems like a bit much for a small piece of plastic, that's the going rate...The bottom line is that these work and are reliable, or at least have been for me (I own 4).Some complain that they have purchased multiple hygrometers and they don't show the same reading, so they must be inaccurate. The truth is that even a top-of-the-line $400 hygrometer is only accurate to 2% RH. So "inaccuracy" is just part of the deal with hygrometers. Regardless, the point of a hygrometer is to determine whether your guitar is in a safe range, not to determine the precise degree of RH.

    The only sure way to know what is really going on inside your guitar case is to employ a hygrometer. The Oasis has alot of promise... but it wasn't the hygrometer for me. It starts with an on/off button that, for me, is useless... to monitor your case, it must be on all the time... and not accidentally turned off. The LED screen is large enough... but the device itself was NOT ACCURATE when tested side-by-side with other similarly priced hygrometers I already have for other guitar cases... it showed a RH that was 50% higher than what the other hygrometers reported, even over several hours and different environments. The temperature reported was the only thing that matched up correctly. The clip's spring tension was a bit excessive... if one were to slide this clip onto the cover/lid of the storage compartment of the case... it would literally crush the lid material. As tight as the clip mounting would be, I doubt it would be removable. If your storage compartment has a hardwood or metal lid/cover, it would be fine. Since the clip is made of spring material, you can not bend it to make a more custom fit... and because the end of the clip has a curve in it, your storage compartment will have its lid/cover permanently ajar, not securely closed. The hygrometer attaches to the clip with the enclosed double-stick tape... a couple of pieces of the Velcro material might be the better mounting for your guitar case compared to the clip. I RETURNED THIS ITEM FOR A REFUND... it might work for somebody who isn't as concerned about their guitars or their guitar cases.

              Comments about Oasis OH-2 Digital Hygrometer w/clip:

              I ordered the whole oasis kit humidifier & hygrometer. This unit is giving me very accurate readings as it is supposed to. I have several different humidifiers and, also some that I have made and, it works well with all of them. Now I know for sure where the humidity level is in each one of my acoustic instruments, Very Helpful. I haven't used the clip just layed the hygrometer in the case about midway between the body and headstock. Glad I have this and, definately would recommend getting one of these if you are concerned about kepping your instruments maintained properly.

              Comments about Oasis OH-2 Digital Hygrometer w/clip:

              Glad I got it, seems reliable and durable. Very handy to use.
              Just a simple hygrometer with a couple of different ways to add or not add a clip. I didn't put on the clip, as I move it around all the time. Seems to have all necessary features, temp, humidity, and shows the high/lows.
              Pretty good little instrument for the price I also have a much more expensive one, and it tends to read about 4 points higher than this one- but you are looking for a range, not spot on accuracy.
              Great value for the money.

              Oasis OH-2 Digital Thermometer and Hygrometer

              from Beaver, West Virginia

              Comments about Oasis OH-2 Digital Hygrometer w/clip:

              As I mentioned in the Quality dialog the thermometer feature is quite good but the hygrometer is very inaccurate. I'm returning the instrument and will look elsewhere for a similar device.
              Digital readout for temperature and humidity are good information and the meter fits nicely beside the guitar neck in my case.
              The concept is great but the measured humidity was always 12-15 percentage points higher than my home hygrometers and they are quite close to what the local NWS station declares.

              Beware of these hygrometers

              Comments about Oasis OH-2 Digital Hygrometer w/clip:

              I love the Oasis humidifiers with the non-leaking gortex, but these Oasis OH-2 Digital hygrometers are junk. I have 2 and they both show different readings than my other hygrometers. Many times they won't give you a reading at all, or they show 0% humidity. I live in Colorado where low humidity is a big problem, especially in winter. A hygrometers that's inaccurate or slow to give a reading is worse than having no hygrometer at all.

                I'm not sure if I got a defective unit, about 65% of the time it displays a reasonable result. The rest of the time it may jump up or down about 80%. So accuracy is VERY questionable.

                    Purchased this about 3 weeks ago to keep in the case of my new Gibson L00. The temperature gauge was way off, usually reading around 105 degrees in a 70 degree room. Over the course of a week I tried different rooms, different environments, etc, nothing worked, always about 30 degrees higher that what it should've read. Tried switching to celsius also, still wrong. (photo below of the closest to actual reading I got) Hygrometer usually ready about 8 % different than my other 2 hygrometers. I get that there can be some variance...but come on.
                    2 emails send to Oasis, 2 weeks later and still no reply.
                    Oh, and the clip that it came with was completely bent, to the point that it wouldn't even stick to the unit when I tried to put it together with the sticky pads.

                            A knowledgable guitar repair guy recommended that I get a hygrometer to verify the humidity in the room where I keep my guitars. The notion is to have an accurate measurement of humidity that is independent of the reading on the humidifier. This unit seems accurate and is small enough to place inside of a guitar case if need be.

                                    My apartment is really dry during winter due to the hit. This measures the relative humidity of my guitars and room with accuracy. Great product.

                                        I like to leave my guitars and Ukuleles out where I can just grab them and play - not locked up in their cases. I worried that with winter, my house heater would lower the humidity too much - so I got a couple hygrometers to put around the house. These (the Oasis) were the only ones that all read the same. The other brands I got were all over the place. I trust these, and now I feel safe about leaving my guitars out. (Heater wasn't dropping the humidity)

                                        I bought one of these awhile ago. It reads about six points higher than my more expensive one, but it tells me what I need to know. Very recently I dropped in on a hard surface, and for awhile it read way off so I quick boughr another. Then the first one started working again, so now I have two. They read within a point of each other, so the reliabiiity is excellent.

                                        Have to wait and see how long it holds up.
                                        Needed accurate humidity reading and this does it. It is only 2% off from my house guage.
                                        It looks like it is made well from the outside, but only time will tell how well it is made.
                                        It was the cheapest digital readout I could find and it is what I needed. So it is a great value.
