BG221553827 The detector arrived before the deadline. It works fine. Unfortunately, there is nothing to compare the measured values to, because there is no standard that I could verify against. I think the measured values are a bit high, but I don\'t know what the percentage tolerance of the detector is and the displayed value is low, /or high?/ I will try to test it in another environment. I think it can still be useful, because the small deviation is not dangerous and if there really is a problem, it doesn\'t matter anyway, but it is important that the detector indicates if there really is a problem.

BG221553827 The packaging is impeccable, the power supply works well.
