The hygrometer has optically very well inserted our sauna of Nordic spruce. The temperature measurement corresponds to the heat detector of the sauna control, so seems to work quite accurately. Very pleasant is the clear and distinct legibility, which leaves to be desired due to the subdued light in saunas with many other displays often left. The colors red and green on a white background with black hands and give a great contrast. One quick look (from the outside through the glass) is sufficient here.
