Since the sensor appears possibly. To be not umspühlt as soon ??
Ordered and tested for several rooms together 4 pieces.
Standing side by side, I can say a big difference between them, with me +/- 1.5 ° C and +/- 5% LF.
In addition, the devices generally exhibit about 5% more humidity as the old which I thought the show right ... The Old scatter not so much on the values.
So tend one can safely measure with that thing (albeit much delayed), but the value displayed can be ensured in question.
