Return Gas Chamber: Uses a multi-pass design that achieves an effective optical path length of 5 meters, significantly improving sensitivity and enabling detection of lower gas concentration limits;

Pulsed Light Source: Adopts a pulsed standard lamp, which is a cold light source. Compared to traditional infrared sources, it offers long service life, high stability, and no warm-up time. Calculated at 3 pulses per second, the lamp can last up to 10 years;

No Optical Moving Parts: Designed without components such as optical choppers or interferometers, ensuring high reliability. On-site vibrations will not damage the instrument or affect measurement accuracy.
