Application Fields

Suitable for multi-level environmental monitoring stations, third-party testing institutions, environmental comparison and acceptance of gaseous pollutants from fixed pollution sources, emergency testing, instrument calibration, self inspection of polluting enterprises such as coal-fired power plants, gas-fired power plants, cement plants, steel plants, laboratory gas detection and analysis, etc.

Performance characteristics

Ultraviolet differential algorithm effectively avoids CO and CH₄Waiting for gas to affect SO₂Interference to ensure measurement accuracy;

Low detection limit, unaffected by moisture and dust, strong anti-interference ability,;

The core components are imported, with long service life and reliable performance;

Constant current sampling effectively ensures constant pressure in the chamber and reduces measurement errors caused by pressure changes;

Configure Nafion pretreatment system for efficient water removal, with built-in ammonia filtration device in the pre-treatment stage to effectively reduce NH₃Cross interference reduces SO₂Loss, reflecting the actual working conditions;

The data processing, storage, query, and printing functions facilitate the understanding of historical and current data, and the data can be exported in real-time for easy comparison and testing;

The internal chamber, light source, and spectrometer adopt modular design for easy portability.
