Greenhouse gas analyzer

The GT5000 Terra high-precision greenhouse gas analyzer is a portable high-precision greenhouse gas analyzer produced by Gasmet, Finland, based on Fourier transform infrared spectroscopy (FTIR) technology. This instrument can simultaneously measure multiple major greenhouse gas components, such as N2O, CH4, CO2, H2O, CO, and NH3, within seconds, and the measurement accuracy can reach ppb level. The GT5000 Terra can be used for measuring greenhouse gas emissions in various environments such as farmland, wetlands, forests, pastures, power plants, and fire sites.

The GT5000 Terra is equipped with powerful Calcmet software, which supports online viewing of measurement results and comparative analysis of past measurement data. The results are output in the form of a spreadsheet, making it easier for users to process the data. Users can easily calculate gas flux based on the measured gas concentration.
