Hesai Drone-mounted Remote Methane Leak Detector is an ultralight and highly sensitive module that utilizes an infrared laser to remotely
detect methane leaks. It can be mounted on the drones, vehicles, and ships for applications such as pipeline survey, residential area
detection, etc.
The detector measures the methane concentration by emitting an infrared laser and receiving the laser reflection.
The reading is expressed by a methane column density (ppm*m). It is the integral of the methane concentration (ppm) and the distance (m)
on the optical path.
