LASEN is the industry leader in airborne methane leak detection, our system is 98% accurate in detecting leaks from 300-500 feet above the ground. Our flight altitude and the speed of the onboard laser allow our helicopters to safely fly at speeds up to 65mph, allowing for 15 times the range of vehicle mounted systems. All inspections include a high resolution video of the entire flight, allowing you to also inspect your Right of Way (ROW) for compliance.
