Good and accurate response

Have checked the hygrometer with a saturated saline solution. The factory setting has thus voted exactly for me to half%. Temperature I was able to check only on the basis of my digital heating control display. Since both approximately show the same value, I'm sometimes assume that this display also shows the correct value. Also by the way can not be calibrated.

Quality and feel
For the price you get a sheet metal body with plastic glazing. Hear now only times as a deterrent to. Still, I find the process consistent. No square edges, no burrs on the air inlet / outlet holes and no wobbling and creaking of the joined components.

You breathed the hygrometer only so increases without any delay to the moisture content displayed. What usually is too sluggish in digital gauges. Finally, I want to get, for example, after 5 minutes airing, displayed the current moisture content and not with a delay of x minutes.

In the package is still a manual for the recovery and / or calibration. If by anyone who has a small flathead screwdriver to be (as I'm also a nail file) perform.

Conclusion:
Otherwise there is not much to say. The thing is doing what it should do and that for a long time reliable and accurate. For me, a strong buy recommendation.
