Continuous Site MonitoringMethane/ethane speciationFully autonomous all-weather operationAutomated leak detection and reporting algorithmsReal-time automatic alarm notification via existing wireless means
Portable Standoff Near-IR TDLAS for Leak Survey
Laser beam illuminates a distant surface Senses analyte gas between transceiver and illuminated
surface Standoff range ~100 ft with handheld transceiver
Scanning laser beam across plume results in rapidly changing analyte gas measurement
~2500 RMLDs™ in use for natural gas leak surveying
