Trusted Performance and Expertise

After independent testing, LI-COR EC instruments were chosen as the exclusive solution for the Integrated Carbon Observing System (ICOS) and the National Ecological Observatory Network (NEON). They are also the most commonly used systems throughout the global FLUXNET community. Much of the credit for the trust placed in our instruments belongs to the scientists who are using them, and the outstanding results they’ve produced. Our team of scientists can help with your research efforts by matching you with the right solution for your needs, and ensuring your implementation is successful.

Made for Real-World Conditions

Finding answers can take your research to far-flung locations, so LI-COR EC solutions are designed to deliver accurate data under demanding field conditions. Systems can be solar powered, and data can be transmitted via cellular and satellite connections to ensure access to measurement data.

Actionable, Configurable Data

LI-COR can help you lead the way in discovery with EC systems that deliver fully computed results—using peer-reviewed best practices—in real-time. You can begin receiving actionable data starting day one.

Flexibility of Solutions

LI-COR EC systems—including both our next-gen and traditional EC instruments—ccan function as standalone solutions or work in conjunction with each other to capture larger spatial scales.

A More Complete Picture

In addition to carbon dioxide flux and evapotranspiration, LI-COR EC systems measure sensible heat flux, latent heat flux, and bio-meteorological (biomet) parameters, providing a more complete, data-rich picture of your environment.
