2 x SITERWELL LCD Carbon Monoxide (CO) Detector Alarm Portable for Travel Home
After a few minutes, the CO detector will display the specific concentration of carbon monoxide. During the test, it is also necessary to note that there is no air flow around the CO detector, which will cause the carbon monoxide generated when the cigarette is not fully burned to be blown away by the air flow, resulting in the constant entry of fresh air in the detector.
