Description

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.

abunda_amazon_reviews I leave my Oasis hydrometer on top of the door in the case so it rests right beside my neck and my case is always laid flat and not upright or sidestood and this hydrometer tells me very accurately what's going on with the temp and humidity in the case which seems to be very accurate at this point. All I did was put in the battery, turn it on and let it get accustomed to the room temp and humidity and just leave it on and place it inside the case. It stays on all the time constantly monitoring conditions inside the case. I use humidipacks but I live in Alabama so when the weather gets more stable and not so much back and forth from hot to cold then I can remove the packs and this Oasis monitor as long as it's on and measuring, should tell me when the time comes around about when to add my humidipacks back for the protection of the guitar. My only complaint is that I'm not putting the velcro sticky part on the guitar or inside the case anywhere by no means so mine just lays on top of the internal door beside the neck. In the future if they could add a cordlike line or string attachment so it can be fixed to the internal accessories door inside the case so it wont move during travel and scractch the guitar or damage the hydrometer, could be a great flexible way of attachment to more desired areas inside the case. When traveling I open the case, lift the guitar, then place the Oasis inside the internal door.;;Reviewed in the United States on April 11, 2019;;5.0 out of 5 stars;;Seems very accurate in the case of my Taylor PS14CE with humidipacks.;;MA573RM1ND;;;The digital hygrometer is OK. Neither the hygrometer nor the humidifier mounts securely. The clip doesn't clip anywhere useful and the sticky mounts don't stick in a decent guitar case. I have used Oasis humidifiers for years but they would mount securely on the strings and never move. I know it is debatable to put the humidifier in the sound hole, but it works for me. This thing doesn't mount anywhere. I tried mounting it in the case using the magnet and adhesive pad, thought better of it after a few hours and came back to find the humidifier had fallen down and ruined the French polish finish on a brand new guitar. I am exceedingly unhappy and won't use these again. Same problem with mounting in the case goes with the hygrometer, because it neither fits with the clip in a Hiscox case nor does it stick securely. Save your money until Oasis fixes themselves.;;Reviewed in the United States on November 28, 2017;;1.0 out of 5 stars;;Very bad mounting system.;;Guitarnuke;;;When I first moved into my new house I felt my lever harp was out of tune quite frequently. After some discussion with my teacher she mentioned temperature and humidity as being primary factors. I have always kept the house "comfortable for a human" which I've often read is "comfortable for a harp" so the humidity became the prime suspect. I now monitor the humidity levels using this hygrometer so that I can nudge into the "comfortable" humidity range using a dehumidifier or humidifier as needed. It sounds high maintenance but harp strings are prone to break - some folks don't bat an eye if they lose 10-15 in a year and that adds up. My harp has only lost one string in almost two years! I'll have to replace them for sound quality before they actually fail. This has also helped me sleep better because when it's very dry at night it's rough on your sinuses. In the winter it can take only hours for forced-air heating to plunge the humidity into the 30s. It's easy to glance at the hygrometer and see if a little humidity or temperature adjustment will make you and your instruments more comfortable!;;Reviewed in the United States on September 30, 2018;;5.0 out of 5 stars;;Monitor your musical instruments!;;Zoya;;;I can understand how the Hygrometer would be off by the way it measures the humidity by the conductivity between two plates with a gap of air between them, and since it is exposed to air, it would be expensive to have them calibrated right away. But digital thermometers are easier to do, since they are measuring changes in electrical resistance. Oasis, allows you to calibrate the humidity, but not the temperature. Three other thermometers say it is 69 degree F, Oasis says it is 76.1 degree F. I laugh at its precision of inaccuracy. More thought and effort went into the manufacture the box and printed matter, than the device.;;Reviewed in the United States on May 22, 2019;;1.0 out of 5 stars;;More thought and effort went into the manufacture the box and printed matter, than the device.;;Evolving_Machine;;;If you are concerned about humidity (or the lack thereof) affecting your guitars or cigars, you need to get something like this that is reliable, accurate and easy to use. It keeps track of the highest and lowest values. Batteries seem to last a long time. Slim design and light plastic might be fragile if improperly left inside an enclosure where it might get damaged. Batteries might be a little tricky to change. The screws to remove the back are very teeny-tiny. I am not overwhelmed by this product but I feel better knowing that I can at least establish a baseline and go from there. I am guessing accuracy is within ten to fifteen percent...close enough. This is meant to measure enclosed cases and not rooms or large open spaces. Comes with a metal clip and adhesive tape for mounting and Velcro for case attachment and restraint. Most experts say anything below 40% humidity could cause damage to fine quality instruments. This unit is affordable enough to own so you can sleep a little better at night knowing your nice Gibson acoustic guitar is not cracking and warping. I am glad I bought it.;;Reviewed in the United States on April 20, 2013;;4.0 out of 5 stars;;Fairly accurate for inside case measurements.;;Guitar Operator;;;I’m using this with a Martin in its case. Recently went out of town for a week. Upon return I could immediately see how well my humidification system held up while I was gone. You can see the range with a few clicks and a glance. This monitoring system let me know that my planet waves humidipak system worked flawlessly with no other active humidification in the house. If you have a solid wood guitar, this is a must have if you’re serious about protecting your investment! The holder keeps the hygrometer where it needs to be.;;Reviewed in the United States on March 3, 2018;;5.0 out of 5 stars;;Works as advertised.;;Richard
