I used 12 other meters and this was waaaay off. It came with a certificate of calibration. There is no way it is anywhere remotely to being accurate. The RH was about 10-15% off and the temp was 10F off. Tested multiple times for many many hours and different conditions. In my bedroom was saying 57 degrees for the temp which is freezing cold, when it was 67. RH in my room is aprox 60-70RH (avg 63-66) outside RH 70+, the meter was showing 45-55. Waaaay off.
