In the current normalization of environmental law enforcement, industrial safety production, municipal operation and maintenance, and emergency management work, the risk of toxic and harmful gases, flammable gases, and volatile organic compounds leakage has emerged in areas such as chemical parks, oil and gas stations, sewage treatment plants, underground pipe galleries, and enclosed spaces. Fixed monitoring equipment is installed in fixed positions, which cannot meet the needs of mobile operations such as multi-point mobile inspection, temporary sampling, emergency investigation of sudden accidents, and on-site law enforcement and evidence collection. Traditional detection tools also have problems such as slow detection speed, insufficient accuracy, and inconvenient portability, which restrict the efficiency of on-site disposal and supervision.
The portable gas monitoring device is an industrial grade portable equipment designed for rapid on-site monitoring of methane and ethane two-component gases. It adopts mid infrared cavity enhanced absorption spectroscopy (TDLAS-CEAS) technology, combined with pump suction sampling method, and integrates a self-developed compact, long path multiple reflection ultra stable cavity. Combined with wavelength modulation and normalization data processing algorithms, it achieves high-precision capture of target gases.
Product features
Accurate gas monitoring
Focus on quantitative monitoring of methane and ethane gas components. Among them, the range of ethane is 0-50ppm,
The accuracy can reach<10pppb, and the accuracy is optimized to 0.5ppb under 5s/5min conditions; The methane range is 0-1000ppm, with an accuracy of less than 20ppb. Under 5s/5min conditions, the accuracy is optimized to 1pppb, meeting the requirements of high-precision monitoring.
Real time online monitoring
Support real-time online data collection and analysis, combined with pump suction sampling method, quickly capture gas concentration changes, and the response time can be flexibly adjusted between 0.1s and 10s, providing timely feedback on monitoring results.
Data transmission and storage
Wireless remote data transmission can be achieved through 5G/NB IoT, or wired transmission through USB, RS485/RS232, making it convenient for users to view and store monitoring data in real time, providing support for subsequent analysis.
Stable operation function
Relying on a professional intake system and an ultra stable chamber design, it effectively resists airflow interference and environmental fluctuations. Its low drift characteristics ensure the stability and consistency of data during long-term continuous monitoring, adapting to the long-term work requirements in complex environments.
Mobile portable monitoring
The integrated design of the portable box does not require complex installation and debugging, and can be quickly deployed to different monitoring points to meet the needs of mobile monitoring scenarios, greatly improving monitoring coverage and flexibility.
