• - Model: LI-7810 CH?/CO?/H?O Trace Gas Analyzer

• Special Features : Measures CH?, CO?, and H?O simultaneously with high precision. Low power consumption (22 W normal operation). Wide operating temperature range (?25 ?C to 45 ?C). Portable design (10.5 kg, 51 ? 33 ? 18 cm). Large onboard memory (stores > 5.3 million records, ~62 days of continuous data). Multiple connectivity options: Ethernet, Wi-Fi (where allowed). Designed for low maintenance with long calibration intervals.

A high-precision, portable analyzer for measuring methane (CH?), carbon dioxide (CO?), and water vapor (H?O) using Optical Feedback Cavity Enhanced Absorption Spectroscopy (OF-CEAS) technology. Offers fast response (? 2 s) and very low drift (CH? drift < 1 ppb over 24 h), making it suitable for both field and long-term unattended operation.
