Gas analysis as part of a measurement system
The rack-mountable format allows the GT7000 Tellus to be installed alongside other instruments in a shared rack environment, where gas analysis is one component of the overall measurement workflow. It is suited for setups where measurements are continuous or repeated, and where stable operation under varying process conditions is a practical requirement. You don’t want any weak points in the setup.
Multi-gas analysis for complex gas environments
Gas composition in real applications rarely stays fixed. GT7000 Tellus measures up to 50 gases simultaneously from a single sample and can identify unknown components from a library of 5,000 gases. The corrosion-resistant sample cell operates at 180°C, keeping the sample in the gaseous phase in the presence of high-water vapor concentrations or corrosive gases. Combined with Calcmet-software, results are available immediately and measurement setups can be adjusted without hardware changes.

Configurable for your measurement setup
Measurement configuration options include:
- Operating temperature: 180°C or 50°C sample cell
- Optical path length: selectable to match sensitivity requirements
- Pressure compensation: for measurements at non-ambient pressures
- Gas components: added or modified through Calcmet software
Part of the Gasmet FTIR product family
GT7000 Tellus continues the next-generation product family defined by GT5000 Terra and GT6000 Mobilis, all based on the same core FTIR measurement approach. Terra is designed for field use, Mobilis for portable flue gas measurement campaigns, and Tellus for fixed, rack-mounted system integration. Measurement performance is validated through EN15267-4 QAL1 certification of the GT6000 Mobilis platform, building on 35 years of in-house FTIR development and more than 7,000 analyzers delivered worldwide. The same technology, adapted for where the work actually happens.
