The Infrared CO/CO₂ Analyzer is a high-precision instrument developed by our factory for detecting toxic and harmful substances in public air spaces. Utilizing non-dispersive infrared technology, it measures carbon monoxide and carbon dioxide concentrations in the air. Featuring high measurement accuracy, extended service life, and minimal cross-interference, it is an essential instrument in environmental monitoring and occupational health surveillance. This analyzer is widely used in environmental protection, environmental monitoring, health supervision, occupational health, disease control, and research institutions.
Features an Android operating system with a 7-inch touchscreen display for enhanced real-time human-machine interaction.
Equipped with high-precision infrared sensors for superior measurement accuracy, rapid response times, and minimal warm-up periods.
Offers extensive storage capacity, capable of retaining over 100,000 data entries.
Supports both nitrogen zero calibration and catalytic zero calibration methods.
Built-in thermal printer for immediate data printing upon test completion.
USB data interface enables data export to USB drives.
Digital flow sensor with real-time flow rate display.
Built-in passage switching solenoid valve for automatic zeroing and measurement switching.
Integrated Wi-Fi for data upload to platforms upon test completion, facilitating data monitoring (optional 4G module available).
Includes internal constant-temperature heating for operation in low-temperature outdoor environments.
Features temperature and humidity measurement with built-in compensation algorithms to eliminate the impact of temperature variations on measurement data.
Displays 0.5-hour averages, 8-hour averages, and daily averages; includes scheduled storage functionality.
