HGA-331 Greenhouse Gases Analyzer

HGA-331 Greenhouse Gases Analyzer

Product overview

HGA-331 is a high-precision greenhouse gas analyzer that can simultaneously measure the concentration of CO2, CH4, and H2O. It adopts Cavity Ring Down Spectroscopy (CRDS) technology, which can effectively measure the optical path up to 20km in a limited optical cavity generator.

HGA-331 can be widely used in online real-time detection of gas concentration such as urban environmental monitoring, regional environmental monitoring, quantitative detection of industrial carbon emissions and other scenarios.

Principle

The HGA-331 employs Cavity Ring-Down Spectroscopy (CRDS) technology, enabling an effective optical path length of up to 20 kilometers within a confined optical cavity. As a result, despite its compact size, the analyzer achieves exceptional sensitivity. Its unique internal temperature and pressure control algorithms endow the instrument with outstanding precision, accuracy, and low drift performance, delivering extremely stable measurements for users.

Key features

• Excellent long-term stability and ultra-low drift.
• Algorithm corrects the dilution effect of water vapor.
• ppb level of sensitivity, precision and accuracy.
• Simultaneous detection of three gases, such as CO₂, CH4, H₂O.
• Performance exceeds half of the World Meteorological Organization (WMO) network compatibility target and meets the WMO internal reproducibility requirement.
• An ultra-compact optical cavity (30 mL) achieves an ultra-long optical path (20 km), with the cavity exhibiting exceptional stability.

Applications

• Industrial carbon monitoring
• Urban carbon monitoring
• Ambient quality monitoring
