a. TDLAS (Tunable semiconductor laser absorption spectrum) technology is used to measure without background gas cross interference;
b. Fast response speed allows it to reflect the measured gas concentration in real time;
c. Compact structure design gives the analyzer no moving parts, good reliability and stability;
d. High degree of intelligence makes it easy to operate and maintain;
e. The optical path realizes uncoupled direction adjustment, and the field optical path adjustment is simple;
f. Good adaptability in harsh environments such as high temperature, high dust, high corrosion and high flow rate;
g. Flameproof design has high safety factor;
h. In explosion-proof places, the menu can be set by isolated magnetic pen, which is easy to operate on site;
i. In-site installation needs no preprocessing system, to avoid preprocessing sampling adsorption, clogging and device damage and other problems.
