I wanted to check the humidity in our homes, because I had the suspicion that the air is too dry. The meter has confirmed this suspicion. Now I can humidify the air in the right amount. The indicator for the humidity is very clear, the temperature can not be seen as accurate. The unit responds very quickly to fluctuations on. It seems to me only the displayed value does not correspond exactly, in comparison measurements it is always a little too low. That was my "precision" presented better in the word.
