QLM-1 – Pan/Tilt Mounted Quantum Gas Sensor

QLM has developed and  commercialised a compact, high-sensitivity, low-power Tuneable Diode Lidar (TDLidar) gas detection and imaging systems based on infrared single-photon detection to meet the needs of natural gas producers, distributors and service providers for fast, accurate and low-cost gas leak identification.



  • Long-range, high-sensitivity, quantitative imaging of gas plume shape and concentration
  • Precise mapping of gas leak locations and flow rates
  • Fixed, mobile, drone and handheld options
  • Solar or battery power options
