Infrared carbon dioxide detecttion alarm

Infrared carbon dioxide alarm is a personal portable CO2 detector and with the sound and light alarm apparatus, apparatus using dual beam infrared technology, measurement accuracy and stability, maintenance free, without calibration, and has a very long service life.

A. Use
Infrared carbon dioxide alarm applies to a variety of ground occasions, such as municipal, chemical, environmental protection site ,etc ,detect the concentration of carbon dioxide gas in the detection environment of the scene, and canmake sound and light alarm. Detect the concentration range of 0 ~5.**0 percent. The instrument has features of a simple operation, small size, portable, high precision and long life. The instrument is intrinsical safe type, explosion-proof logo is ExibI (**0 ° C).

B. Measurement Principle

Apparatus adopted double beam infrared measurement principle, the structure shown in Figure 1

Processing signal outputed by Infrared sensor ,will be setted and operated after entering the single-chip microcomputer controller, and the results will be displayed on digital display screen, when the concentration of carbon dioxide exceeds setted concentration alarm point (1.**0%CO2), apparatus will generate sound alarm and flashing light signal.
