5 Best Carbon Monoxide Detectors Reviews of 2021 ...

2021-05-23· 2021-05-23· Since carbon monoxide is lighter-than-air gas, it may take some time for it to concentrate in the room before CO levels become dangerous. That is why it's vital to take measures long before the problem occurs. The Kidde KN-COB-B-LPM CO Alarm can be a good solution to opt for considering its price, convenience of use, and efficiency.

Why do I See Negative Readings on my Gas Monitor?

2019-09-18· technology that makes gas detection easy. Negative readings may also occur when the sensor is exposed to a gas that produces a negative cross interference. If a sulfur dioxide sensor, which typically has a -100% cross interference to nitrogen dioxide, is exposed to 2 PPM NO2, the resultant sulfur dioxide reading on your instrument will be -2 PPM.
