Product review (5 stars): Rapid response
This is the only device I have to measure humidity, so I'm assuming it's correct. Temperature seems accurate as it's reading close to what I have the thermostat in my house set to. I had having some condensation issues in my home and wanted something to also measure the humidity so I could better study the psychrometrics. The meter is very sensitive; picking it up will raise the humidity a few points almost instantly. When I discovered that, I began breathing on it to find it could raise the meter to 95% rh. Anyway, nice to have this extra data now so I can finally take care of the humidity issue in my home.
