when you sit next to your pc, have you ever messured the CO2 ppm ?
asking because i recently got a co2 messure (uni-t A37) and it shows damn high ppm in my “office” room.

yes. yours has a automatic baseline calibration. those are the “cheap ones”. put it outside for 3 days and it should reset iteslf
