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.
@Krauerking you could look at calibrating the hygrometers or at least the offset.

Two point calibration with calcium chloride and sodium chloride might be even more accurate
Nah these do not have a calibration method.
Cheap and seemingly what the average consumer uses based on the 3d files all using them but not calibratable and wayyyyy off.
@Krauerking ah but you can measure the offset. A two point calibration should cover your measurement range. Not ideal but you could get a reading.
Yeah I did measure all their offsets actually already in a rougher method than the salt water trick. I’ve so far got
+27, +18, +14, +13, and +7 and 1 that is within +1 margin of error.
I dunno that just seems like a waste of electronics components. I can use them but… Yuck right?
