The hazardous gas remote sensing and imaging alarm system utilizes passive Fourier transform infrared spectroscopy analysis technology, utilizing infrared fingerprint characteristics for remote sensing detection of gas clouds. Identification software enables rapid qualitative identification and quantitative inversion of hazardous gases, enabling day and night scanning and imaging of the detection area, providing highly sensitive and rapid identification and alarm of hazardous gases.

The product can conduct fully automatic remote monitoring day and night within a 3-kilometer radius, quickly qualitatively and semi-quantitatively identifying various toxic, harmful, flammable, and explosive hazardous gases. It can be used together with tripods or can be installed on the emergency rescue trucks to carry out mobile monitoring for dangerous areas of the accidents. It displays test results in real-time graphics and text, issues instant alarms, and visualizes the distribution and diffusion trends of hazardous gases in the air, assisting in the search and location of leak sources and providing a basis for decision-making in on-site monitoring and emergency response. It has been purchased and deployed by fire rescue units in many provinces and cities. 

We have the most complete set of products including portable type(for single person use), mobile type(to be used with tripod or emergency rescue truck),fixed type( 24*7 non-stop monitoring for chemical and refinery plants) and UAV type, which caters for users’ different needs and application scenarios.
