Main functions

1. The high-precision gas analyzer is based on Cavity Ring-Down Spectroscopy (CRDS) technology, designed for continuous monitoring of methane (CH₄), carbon dioxide (CO₂), and water vapor (H₂O) with ppb-level detection sensitivity;
2. Delivers ultra-low detection limits (CH₄ <0.05 ppb; CO₂ <0.1 ppm) and exceptional long-term stability (<1% annual drift). The system features built-in temperature and pressure compensation, supports synchronous multi-component measurement, and incorporates automatic calibration with integrated fault diagnostics;
3. Widely deployed for urban greenhouse gas monitoring, landfill emission assessments, agricultural methane source attribution, and climate change research applications
