Unfortunately, after living with this unit for several months, it doesn't seem to be very accurate. I have four digital hygrometers in my home. Two that are part of larger wireless indoor/outdoor weather stations, a cheap one from Harbor Freight, and the Oasis. I set them all in the same location and waited a couple of hours to see what would happen. The two weather stations and the HF cheapie agreed to within a percent. The Oasis read 5% lower than the others. This is not a big deal except that you're aiming for a specific value in a guitar case and an accurate instrument would be helpful in doing that.
I sent this first unit back to Oasis and to their credit, they supplied a new one quickly at no charge. Sadly, this new unit reads even lower than the first, 8-10% lower than any of my others. The only reasonable conclusion I can make is that all Oasis hygrometers simply read low, and in a guitar case application this will cause you nothing but angst and uncertainty as you try and get the humidity in the case up to the recommended 45-48%.
There are small, inexpensive hygrometers out there that are settable and can be user calibrated, and I think this a better solution than the more expensive and inaccurate Oasis. I originally gave this item 4 stars but have now reduced that to one. If an instrument does only one job, but does it poorly, what good is it?
Currently I use 5 hygrometers. 3 of them are this Oaisis model. Like the Q&A discussion, I have run tests with the 3 together and the group of 5 together. There is some minor variation in the side by side reading on the Oasis, and there is some minor variation among the 5.
I use these hygrometers for guitars. They are used inside hard cases with up-to-date humidipaks installed. If I have a guitar out of the case for a day or more, the hygrometer is hung in the Oasis string holder right next to the sound hole. The room with the guitar rack is also monitored for room temperature and humidity.
The minor variations on these hygrometers become inconsequential in the context of overall monitoring. My guess is that those of you who have real concerns about monitoring have multiple methods and are generally cautious. Some spend more for greater accuracy AND precision. I am satisfied that the Oasis is a successful part of my guitar protection program.
If you are looking for a single solution for your guitar's health, this will likely give you a reasonable solution. It will assure you that you have access to the warning signs of a moisture and heat/cold environment that may be toxic to your instrument's health.
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.
