GASEX PORTA
Autonomous Stand-alone Portable FTIR – for gas analysis
Arcoptix presents GASEX PORTA I: GASEX PORTA I is an autonomous FTIR gas spectrometer optimized for on-site or laboratory operation. Its core consists of the OEM GASEX unit comprising a powerful couple of our vacuum tight “Rocket” FTIR spectrometer, integrated to a low volume (0.2L ) heated gas cell providing five meters long optical path in your gas sample. GASEX PORTA is equipped with LiPo accumulators providing energy for up to 8 hours of autonomous operation
Features
GASEX PORTA includes:
- Compact, rugged and high-performance FTIR module with 4TE-MCT detector;
- Long path (5m), low volume (0.2L) heated gas (190°C) cell seamlessly matched to the FTIR for high sensitivity and very short response time;
- Rhodium coated chemically resistant optics
- LiPo accumulators for up to 8 hours of off-grid field operation.
- Optionally powered from 12 V or 24
- USB2 or optionally WiFi connection for communication with your PC.;
Application fields
