In case hygrometers?

For individual uke monitoring, I've been using this one, usually used for egg incubation... w/ probe in the case & display outside the case.

I have 2 free standing/wall traceable® hygrometers, which can be sent in for calibration periodically https://www.traceable.com/calibration-info. Any individual hygrometers I add can be checked against the traceable ones for ballpark accuracy.

Thanks Jerry. Don't know why I didn't think to look it up. Too many things to do and so little time I guess. Like practice?

I bet a regular digital room thermometer would also work. Of course, I would check it for accuracy. If it's not accurate, the test will let you figure the percent of error. You can work with that percent, rather than returning it trying another one.

Thanks for the tips, everyone. I am going to try the egg hygrometer--I can run the sensor into the case and into the sound hole alongside my humidifier.

As a result of this thread I purchased two of the Oasis hygrometers for my cases this winter. I have a room analog hygrometer that I have used for the past several years (I do humidify the room during the winter).So I put the two Oasis next to where I play and they both read 52%. The analog is reading 62%. So I play for a half hour or so and the Oasis now reads 45%. This keeps on for several days. Yesterday I realized that when I play I turn on a lamp. Wonder if the heat from the light affects the hygrometer. So I move one of the Oasis several feet from where I play.. It now reads 68% (it is very humid outside here today and I have a window open). The Oasis where I play next to the lamp is 52%. Just an FYI abut where you should be placing your hygrometers.

Just how precise must one be with the humidity to ensure that their ukulele is being cared for in a reasonable manner? How much time does it take for the ravages of dryness to destroy a ukulele? Does it take minutes, hours, months, years? I have my own opinions based on my own very limited experiences.

Thank you Wukulele! I was wondering if anybody had used a hygrometer with a probe to monitor the humidity inside a case without having to open it. I thought it would be a good way to determine if a humidifier* is effective. MopMan, how did it work out for you?

I use this, and really like it. https://smile.amazon.com/DAddario-H...io+humiditrak&qid=1554648625&s=gateway&sr=8-1

I like the Happy Farm hygrometer. It measured down to 12%RH over the winter in Pennsylvania. It is registering about 35%RH now, in early April. I cannot prove its accuracy level, but it registers a good range so I trust it gives a fair indication.

It is easy to string the sensor down into a ukulele sound hole and leave the display outside of a closed case for quick reference without opening the case.

Using the Happy Farm this past winter, I was able to determine that the Oasis ukulele humidifiers I use easily take a soprano uke up to around 50%RH(according to Happy Farm) within a few hours. Tenor ukulele, however, only made it up to around 40%RH(again, Happy Farm units) inside the body of the instrument after a full day. For me, this was confirmation that both Oasis and Happy Farm were doing their jobs satisfactorily.

I would recommend the Happy Farm hygrometer to anyone. It has been an easily workable and problem-free tool for me so far.


EDIT: Here is a link to the Happy Farm hygrometer on Amazon. Many thanks to Wukulele for the find!

Gonna grab a few of these FROM Amazon. Plan to secure on the top lid inside the case, above the headstock, with a small patch of velcro glued onto both the unit and the case. The are small, only 1.77" x .5".
