What is a portable infrared gas analyzer? What is it used for?
The portable infrared gas analyzer is designed based on the principle that different gases selectively absorb infrared rays. Adopt foreign advanced correlation filter technology (GFC). It can quickly identify volatile organic gases, flammable gases, toxic industrial chemicals and gases, corrosive gases, pesticides, chemical warfare agents and other gases in the environment.

The instrument monitoring probe uses a lead selenide probe with high infrared absorption efficiency. It has a built-in semiconductor cooling element to balance the temperature inside the probe, so it has little impact on outdoor temperature changes. The probe has a long service life, high precision, and fast response speed.
The portable infrared gas analyzer has two built-in analysis sides, sharing a gas chamber, cross-analyzed signal spectrum, one side as a reference signal, and the other side as a signal to be measured, and subtracting it through a digital logic circuit to obtain the signal of the measured gas At this time, the change of the signal concentration is the gas concentration value. The signal is converted into a voltage signal, and after gain amplification, the data is linearized by 20 segments of the microcomputer, so that the accurate concentration of the gas is displayed on the display.
The portable infrared gas analyzer adopts the international advanced infrared correlation filtering principle. It is an easy-to-carry infrared gas analyzer with fast response and stable performance specially designed for environmental protection research units. Moreover, its detection range is wide, and its concentration can be accurately measured from trace level (PPM) to constant level (%). . It is very suitable for various health and epidemic prevention supervision departments, industrial labor protection departments, environmental monitoring departments and other scientific research units to detect the concentration of carbon monoxide, carbon dioxide and other gases in the gaseous state.
