Main features of carbon monoxide alarm
Carbon monoxide alarms can be divided into household carbon monoxide alarms and industrial carbon monoxide alarms according to the direction of use. In addition, they can be divided into wall-mounted/fixed carbon monoxide alarms and portable carbon monoxide alarms according to their usage. You can choose different according to your different requirements. Instrument.
The carbon monoxide alarm converts the concentration of carbon monoxide gas in the air into an electrical signal through a carbon monoxide sensor. The size of the electrical signal is related to the concentration of carbon monoxide. Carbon monoxide alarms are classified according to the sensors used. They are generally divided into semiconductor carbon monoxide alarms, electrochemical carbon monoxide alarms, infrared carbon monoxide detectors, etc. The performance is the best in terms of measurement sensitivity, accuracy, stability, and resistance to cross-gas interference. This is an infrared carbon monoxide detector, but it is more expensive and suitable for laboratory use. The civil use is generally semiconductor and electrochemical carbon monoxide alarms.
