Hazardous gas leak incidents typically involve complex compositions, high risks, and areas inaccessible to personnel. Emergency management departments must develop incident response plans based on the composition, concentration, and location of the leaked gas. Sailhero has independently developed the XHRFTIR6000 passive Fourier Transform Infrared Spectrometer, featuring high reliability, high speed, and high performance. Building upon this foundation, the system integrates high-precision field-of-view scanning and visible-infrared channel match
