I think the first step would be to buy a second monitor, ideally from a different manufacturer, and verify that your readings are actually correct. My experience is that cheap monitors are basically random.
- lazide 3y agoAt least one (Big Clive pulled it apart I think?) had an Ethanol sensor in it.
