These have to be the least accurate things I have ever seen.
The rectangular one is accurate or accurate enough and has been what I used but I noticed files all had cutouts for these round hygrometers…
Well from my 6 pack 1 is within a margin of error to even be useful.
I get they aren’t expensive but seems like a waste of money for this bad.
DampRid? Wait I already have calcium chloride then.
Ok well I guess I can test if they even scale right but I’m not holding my breath around them, I’m not sure the extra humidity I breath out anyways would register on these.
I really think I might just take the batteries from these and call it a loss and use better components.
Thank you for the testing info! Actually really helpful.
