ATEX Portable gas analyser Geotech GA5000

The Geotech GA5000 is a portable gas analyser designed for landfill and contaminated land monitoring. Certified to international standards, it provides accurate measurement of up to six gases, including CH₄, CO₂, O₂, with optional H₂S, CO, NH₃, and H₂. With easy calibration, modular design, and robust construction, it helps operators standardize monitoring routines, ensure compliance with environmental legislation, and deliver reliable on-site results.

Key Features

• Certified: ATEX, IECEx, CSA, MCERTS, and UKAS calibration (ISO17025)
• Simultaneous measurement of up to 6 gases (CH₄, CO₂, O₂ + optional H₂S, CO, NH₃, H₂)
• High accuracy: ±0.5% for CH₄ and CO₂ after calibration
• Measures barometric and relative pressure
• Fast response times (CH₄ and CO₂ ≤10 s, O₂ ≤20 s)
• Modular and upgradeable design
• Data logging: up to 2,000 IDs and 4,000 readings (with GAM software)
• Profiling and event logging functions
• Choice of additional gas ranges (H₂S up to 10,000 ppm, CO with H₂ compensation)
• Optional: borehole gas flow, flow logging, GPS, ATEX-certified anemometer, temperature probe
• Rugged IP65 case for outdoor use
• Clear 4.3” full-color TFT display
• 3-year warranty, 12-month service interval
• Powered by rechargeable NiMH battery (8 h operation, 4 h charge time)

Applications

• Landfill gas monitoring – CH₄, CO₂, O₂, H₂S, and CO for compliance and control
• Waste-to-energy plants – biogas measurement and optimisation
• Contaminated land investigations – gas analysis for remediation projects
• Environmental compliance – supports legislation monitoring and reporting
• Borehole monitoring – gas flow and composition analysis
