CRDS Laser-Based Analyzer
COMBAT GLOBAL WARMING AT THE SOURCE
A compact and user-friendly solution for monitoring ambient levels and emissions of methane
Our T-I Max™ AIR CH4 greenhouse gas (GHG) analyzer for methane is designed for versatile use. It can measure ambient levels of CH4 with high precision over a wide range of temperatures with excellent reliability, and they can monitor emissions of greenhouse gases from various sources such as landfills, gas and oil exploration sites, refineries, and agricultural facilities. The T-I Max AIR helps users to easily and accurately assess their GHG emissions and implement measures to reduce global warming. Using our T-I Max AIR analyzer, you can measure ambient levels of methane with parts-per-billion accuracy, drift-free stability, and fast response. You’ll find our systems fast to install, exceptionally easy to use, extremely reliable, and effortless to maintain due to their built-in calibration verification. The robust design—free of moving parts—results in an analyzer that has a high mean time between failure (MTBF) and a very low cost of ownership (CoO).
BENEFITS
- Accuracy traceable to the world’s major national reference labs
- Specificity—no moisture or other interference
- High precision at ambient or even higher levels
- Freedom from the need for span calibrations
- No periodic sensor replacement/maintenance
- Wide dynamic range and no drift
- Compact and rugged design
