Line-of-Sight Detection

Open path monitoring provides continuously updated, real-time, path-integrated concentrations across a facility boundary that can be used to generate an estimated emissions rate. This provides a much more complete picture of the estimated fugitive emissions across that boundary, enabling identification of specific operations and times that give rise to higher emissions, therefore enabling these emissions to be properly managed and controlled.


Boreal’s Open Path-Tunable Diode Laser (OP-TDL) technology provides continuous and instantaneous response times and accurate readings of targeted gases without false alarms caused by cross sensitivity to other gases or atmospheric interference. This is an operational-friendly technology as it has a lifespan of over 15 years and does not require inherent calibration.
