Since I had three units ordered, of course I was able to compare with each other. They were put into operation and placed a few hours next to each other and in three different environments in terms of temperature and humidity. After a short time I had the ads at the temperature 1 degree (here are some consistent values displayed) and the maximum moisture 0.2% (here is still a decimal display) were different. That's in this price range - although only a comparison among themselves - unusually well.
When Feuchtigkleit I had no absolute comparison (calibration), however, made the basis of certain factors sense. When the temperature (here I have a very expensive piece of equipment to compare) agreed it exactly to the degree.
Date and time actually I do not, and maximum and minimum values only conditionally need (actually I only need moisture) but it also does not bother to have this information along. But who creates a record of the moisture development, has here all necessary data at a glance.
With the setting you have the usual problem - three buttons for twenty functions (1x, 2x, 3x press) but that is now standard. Yet even this is slightly out of hand because something is not supplied with self-evident: a clean print, readable font size even without a magnifying glass, multilingual user manual in plain language.
Well, and then I could even the 5-Euro Schott readjust to hygrometers and needles are available in reasonable relation to the facts.
The filigree wall mount is to be treated with caution and the only criticism. Here one must be careful not to happen what happened to me (although I had already seen the danger in advance) and the unit falls down (the unit mounted and the holder has moved away from the wall). The 1.50 meter height of the fall on the concrete floor in the basement has put away the device and continues to function properly. Nevertheless, you could have the better solve. So after buying careful. Perhaps the windy mount not just hang on the wall, but attach correctly with a screw. Then, if necessary, a little bend to hang around the appliance!
