20211124· Therefore, the lower detection limit and longer service life of semiconductor gas sensors are A better choice for home alarms. ②The catalytic combustion type carbon monoxide sensor has high accuracy and is suitable for quantitative detection in coal, petroleum, chemical, gas and other fields. But its working temperature is high, the catalyst is easy to deactivate, and at the same time, the ...

A CO detector is just a small box with a carbon monoxide sensor and an alarm inside. As soon as the safe carbon monoxide threshold in the room is exceeded, a chemical reaction in the detector creates an electric current, which then sounds an alarm.

Carbon Monoxide is virtually the same weight as air and therefore the alarm protects you in a high or low location. For maximum protection, a carbon monoxide alarm should be located outside primary sleeping areas, in sleeping areas and in each level of your home. Where NOT to Install a CO Alarm . Some locations may interfere with the proper operation of the alarm and may cause false alarms or ...

Carbon monoxide. Carbon monoxide is a product of combustion. It is also the most common cause of occupational gas poisoning leading to death. It is hard to detect because it has no colour or odour. It is especially dangerous in confined or poorly ventilated spaces. Recognizing the symptoms of carbon monoxide poisoning can prevent fatalities.

Carbon Monoxide Poisoning Carbon monoxide (CO) is a poisonous, colorless, odorless and tasteless gas. Although it has no detectable odor, CO is often mixed with other gases that do have an odor. So, you can inhale carbon monoxide right along with gases that you can smell and not even know that CO is present. CO is a common industrial hazard resulting from the incomplete burning of material ...

25 ppm. Maximum allowable TWA exposure limit. OSHA. Used in personal CO alarms. 30 ppm. 30 Days. Nonresponse level for CO detectors over 30 days. Home CO detector alarms are designed to not sound when exposed to 30 ppm (or less) of continuous carbon monoxide for 30 days in order to avoid nuisance sounding.
