Looking for a small, but accurate, humidity meter to keep in a flute case or Tupperware box (that holds the flute case) to ensure that things aren't drying out. Any suggestions?

Thanks and best wishes.

Steve

I guess I'd check online. Makers often send these along with their flute, so might
be glad to sell you one, e.g. Dave Copley. These are, as you probably know,
simple, small devices and are probably pretty cheap.

I've used this one for years - it's great - cheap, accurate, and small enough to fit it what I use, a bait box with adjusted dividers.

Thanks for the input thus far. It's the accuracy that is significant. I have several inexpensive meters and sitting side by side they read up to 20% different at any given time. Some will go up and some down with changes in weather—again sitting side by side.

Best wishes.

Steve

I have an Oasis like this (similar to Pat's Caliber IV) for my case when I'm out/away:
https://www.amazon.com/Oasis-Digital-Hygrometer-replacement-Calibration/dp/B075KMHQ4L/

And three of these (under the original Dostmann name) for 1. the room where I keep my wooden flute, pipes and recorders, 2. my living room and 3. my outside shed workshop:
https://www.amazon.com/Crosse-Technology-30-5015-Digital-Thermo-Hygrometer/dp/B000K2DBLS/

So, while not suggesting these Dostmann devices for a flute case, what I can tell you is that all four read within 2% or so of each other when placed together. Can't vouch for absolute accuracy and can't remember if the Oasis reads lowest or highest (have just switched it on beside one of the others and will report back when I've got stable readings), but can vouch for acceptable consistency between the four.

Edit (100 minutes later): just been back to check three together and, while I stood and watched...

One Dostmann started at 13.7°C 63% RH and moved to 13.8°C 64% RH.
Another Dostmann started at 13.7°C 61% RH and moved to 13.8°C 62% RH.
The Oasis started at 13.4°C 62% RH and moved to 13.7°C 64% RH.

The third Dostmann is out in the workshop so I didn't bring it in. Draw your own conclusions from the figures, but I'd say they're at least consistent with themselves and all close enough together to suggest some kind of common standard if not the kind of absolute accuracy that might cost orders of magnitude more.

The Oasis is far quicker to react to big changes (e.g. being moved to a new room), which I'd say is useful when that's my travelling device and the others normally live in fixed spots. But the Dostmanns are better as always-on, see-across-the-room devices, which is what I bought them for.

You've got heavier sweaters than I do.

Interesting (to me at least) that the Burgess site demo of disagreeing meters shows three of the very ones I've been trying to use—and their strongly divergent opinions. Hence my interest in trying to find something at least kinda accurate.

Appreciate the input.

Best wishes.

Steve
