Portable CO2 analyser Gas Data GFM 226

The Gas Data GFM 226 is a compact, rugged portable CO₂ monitor (with optional O₂) engineered for fast, reliable air-quality and confined-space checks. Lightweight and easy to carry, it delivers clear readings in low light, long battery life, and simple sampling accessories for rapid field deployment.

Key features

• Infrared CO₂ sensor: 0–10,000 ppm range, 10 ppm resolution (site kit accuracy per manufacturer)
• Optional O₂ sensor: 0–25% range with 0.1% resolution for oxygen monitoring
• High-contrast backlit LCD for clear viewing in the field and low light
• Portable, one-hand operation with weather-resistant neoprene carrying case included
• Long battery life: typically 8–12 hours continuous operation; fast re-charge (~4 hours)
• Optional data logging and USB download (via data logger accessory)
• Sample accessories available: needle probe, under-door probe, 1 m lance, and exhaust/bag sampling connector
• Rugged, field-ready construction designed for routine site use
• Recommended annual recalibration / 12-month service interval to maintain accuracy

Applications

• Hidden-person / stowaway detection in vehicles, containers and hold spaces — detect elevated CO₂ and reduced O₂
• Confined-space air-quality checks before entry (storage tanks, chambers, vessels)
• On-site safety checks during maintenance, transport inspections or security screening
• Portable CO₂ monitoring for rental fleets, rapid site assessment and emergency response
• Environmental and occupational screening where quick, portable CO₂/O₂ readings are required
