Drone-based laser methane remote sensor

Retail price

Market price


The HJ-CH4 is a lightweight, high-sensitivity gas detector based on tunable diode laser absorption spectroscopy (TDLAS), capable of rapidly detecting methane at concentrations as low as 5 ppm·m from up to 300 meters away. This device ingeniously integrates and precisely calibrates both the detection laser and a visible-light sensor, enabling accurate laser-based methane measurement alongside complementary visible-light verification. Coupled with pan‑tilt intelligent stabilization technology, it swiftly delivers critical information to users, helping them seize opportunities and elevating both their sensing capabilities and operational efficiency to a new level.
