Long-Range Emissions Monitoring with Open-Path Laser Analyzers

Measure trace gases like methane and ammonia across barns and fields with unmatched precision, speed, and spatial coverage.

Open-Path Laser Gas Analyzers

AgroEnviroTest’s Open-Path Laser Gas Analyzers offer an advanced solution for real-time, long-distance trace gas monitoring across agricultural environments. Utilizing tunable diode laser absorption spectroscopy (TDLAS), these systems emit laser beams across open air to detect gases such as methane (CH₄), ammonia (NH₃), and nitrous oxide (N₂O) with extreme accuracy. Ideal for large-scale applications—such as livestock barns, manure storage areas, and crop fields—this technology eliminates the need for physical sample collection, offering continuous, non-intrusive data collection. At AgroEnviroTest, we empower farms, researchers, and environmental agencies to monitor emissions more intelligently and effectively, helping to ensure regulatory compliance and reduce environmental impacts. 

Hardware

High-precision laser transmitter and receiver units are enhanced by Optical & Imaging Sensorsfor accurate plume detection near insured facilities and risk zones.

Adjustable tripod or mast-mounted configurations utilize Zigbee Accessoriesfor secure, wireless alignment and positioning in dynamic insured environments.

Weatherproof enclosures for outdoor durability integrate with Wi-Fi HaLow End Devicesto ensure resilient, long-range data relay in remote financial asset zones.

Integrated GPS for spatial referencing is supported by GPS IoT Trackers/Devicesto geotag emissions sources around high-value, underwritten locations.

Solar-compatible battery systems for remote use rely on Cellular IoT Devicesto maintain continuous connectivity and emissions reporting from off-grid insured sites.

Case Study

Dairy Emissions Project – California, USA

A Central Valley dairy partnered with AgroEnviroTest to monitor ammonia and methane from manure lagoons using open-path laser analyzers. The resulting data supported an improved waste management plan and reduced the farm’s total emissions by 27%. 

Swine Facility Odor Mitigation – North Carolina, USA

A pork producer deployed our system across multiple barns to track odor-causing gases and validate mitigation strategies. Our real-time data helped secure local zoning approval for an expansion project. 

Crop Research Station – Alberta, Canada

Researchers at a University of Alberta agricultural research station used our analyzers to evaluate nitrous oxide flux in no-till wheat fields. The precision of the data enabled them to publish findings on the environmental trade-offs of tillage systems.
