Very good deal! Displays temperature and relative humidity in large digits on - including small are still the current time and date. The recording of the temperature and humidity works great - the interval can be adjusted (15min - 30min - 1h -, etc.). The recorded data can be accessed on the same device (with each press of HIST can value by 1 back jumpers in history - with the checkmark button forward again). Furthermore, the data can be transferred and analyzed via included USB stick to the PC (I have not yet used). So exactly what I wanted.
