LK-2400 Portable CO2/N2O Flux Measurement System

The LK-2400 Portable CO₂ and N₂O Flux Measurement System utilizes Mid-Infrared Absorption Spectroscopy (MIRAS) technology. By leveraging the strong absorption characteristics of target gases in the mid-infrared (MIR) band, it analyzes gas concentration information, achieving ultra-high sensitivity and precision monitoring within seconds. The system is paired with an automatic soil flux chamber for in-situ measurement of soil respiration rates. It can also be connected to static chambers, mobile water surface flux chambers, and other accessories to meet various measurement scenario requirements.

Key Features
