It seems to be working. I’ve only checked the windshield washer fluid so far. But I don’t understand a bit, because the concentrate says -80. ° S, and the device showed approximately -43 degrees. ° S.
Maybe it needs to be calibrated somehow.
It’s impossible to open the box with your fingers; you have to use a screwdriver (well, something like that).
I will try to check other liquids further…
