Principle
The main components of LGA-8100 analyzer include laser transmitter, laser receiver, purging unit and junction box. The transmitting unit emits infrared light and uses an optical lens to guide the laser through the environment filled with the detection gas, then the receiver gather and reflects the infrared light carrying the optical information, and finally, the electronic component decodes the received signal into the gas concentration.
