The PRI-5251f is a cutting-edge, high-precision, multi-component solution designed for aerial greenhouse gas monitoring. This integrated system features a high-precision analysis module, a miniature meteorological station, and the ELF-600 hexacopter UAV. It enables simultaneous, real-time measurement of three primary greenhouse gases (CO₂ N₂O CH₄) and water vapor (H₂O), alongside 3D ultrasonic wind speed, air temperature, humidity, and atmospheric pressure.

At its core, the PRI-5251f analyzer utilizes an innovative miniature laser sensor engine. By leveraging strong spectral absorption in the Mid-Infrared (MIR) band, the system delivers high accuracy and a wide dynamic range with ppb-level sensitivity. The system is specifically optimized for size, weight, and low power consumption, making it the ideal payload for miniature UAV platforms.
