The hygrometer TFA 30.5005 is very compact (53x39x16) and has a delicate, table stand to place it at an angle of 45 ° can. So the reading of the display can be facilitated. By pressing the "Max / Min" you can switch between the display of the current, minimum or maximum reading. Via a second button Clear the stored extreme values is possible. It responds quickly to temperature and humidity changes and the display appears to be relatively accurate because my two devices have displayed after a short time identical values. The device gets to me only 4 stars because I display the temperature in tenths of a step and the ability to Aufängen on a nail (a double-sided tape included) is missing. Furthermore, the second device keys not used properly so that they can be operated somewhat hakelig. I can recommend this device, the search for a none, inconspicuous and (seemingly) accurate hygrometer to check the humidity in his home, and can live with the limitations mentioned above.
