The instrument provides fast response, high-precision flue gas measurement, and real-time calculation of key combustion indicators, helping engineers improve system efficiency, reduce fuel consumption, and support regulatory environmental compliance.

Equipped with a cross-interference compensation system, ensuring accurate detection.
It can be adapted to install two sensors of the same type but with different concentrations, allowing for instant switching between high and low concentration detection modes.
Can replace the same gas sensors or add new gas sensors in site if the customer can do calibration by standard gas ; needn't send back to factory.
The instrument features automatic sensor detection and zero-point calibration upon power-on.
Three-stage treatment system: High-performance self-developed Peltier cooling system (optional), automatic water vapor separation device, and high-end water cutoff filter.
Equipped with a built-in Beidou positioning and satellite timing system, the data is traceable and verifiable.
The measurement process can be monitored remotely via mobile phone; an optional Bluetooth printer is available for automatic printing of average measurements.
This highly integrated, low-power device features a built-in rechargeable lithium battery, providing up to 8 hours of continuous operation. It can also be charged while in use.
Monitoring data: complete, accurate, and traceable; parameters and logs are recorded fully automatically.
Features include adaptive measurement for sensor overload, data encryption for storage and export, and interfaces such as a memory card slot and Type-C port.
The built-in instrument diagnostic program can monitor various instrument performance parameters in real time, such as airtightness self-check and sampling flow monitoring.
