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.

    Mine are pretty consistent, max. 5 percent points difference between them. Cheap brand from a big internet warehouse.

      Lucky. Pretty sure these are the same from the same internet source but the swing on them is insane. They all showed as 75% in the bags but spending some time with them I realized the complete lack of accuracy when I realized my humidity wasn’t what it was reading.

      I have since taken some apart and cleaned them out but now those are just under the humidity by the same percent they were over before.

        The analogue one I own (round body) can be tuned/adjusted by a small screw on the back. Maybe that’s an option?

          Not with these cheap electronic ones. Looks like there might have been a missing connector for resetting the RH value and a missing button to swap between F and C for temp.
          Part of my calling these out as they seem very much useless.
