Model LI-7700 -Open Path CH4 Analyzer

The LI-7700 makes in-situ measurement of methane density with the resolution, speed, and stability required for the eddy covariance technique. Previously, measuring methane flux was difficult because of instrument limitations, including high power demands, heavy pumps, and the need for instrument enclosures. The LI-7700 overcomes all of these limitations. The LI-7700 is light weight, has low power requirements, and provides high frequency response. The LI-7700 is designed to measure methane density at frequencies that are necessary to quantify ecosystem methane flux.
