Gasmet GT5000 Terra – Portable Multigas FTIR Analyzer

The Gasmet GT5000 Terra is a compact and portable Fourier Transform Infrared (FTIR) gas analyzer for field and research use. It measures up to 50 gas compounds simultaneously, including CO₂, CH₄, N₂O, NH₃, and H₂O, providing laboratory-grade accuracy directly on site.

Designed for environmental and soil gas studies, industrial hygiene, and emission research, the GT5000 Terra combines high analytical performance with rugged, field-ready design. The analyzer operates via Calcmet software, offering real-time data visualization, calibration, and remote operation.

Key Benefits and Applications

  • Simultaneous multi-gas analysis (up to 50 compounds)

  • Ideal for GHG flux and soil gas research, industrial hygiene, and emission studies

  • Real-time spectra and concentration data via Calcmet Easy/Expert software

  • Portable and lightweight (9.4 kg with battery) for field deployment

  • Multiple connectivity options: USB, Ethernet, Wi-Fi, Bluetooth

  • On-board sample pump (2 L/min) and integrated Li-ion battery for up to 3 hours of operation

  • Remote controllable via Wi-Fi Access Point or Wi-Fi Station modes

  • Compatible with FluxScout chamber systems and Sense Gas units
