The LI-7700 Open Path CH4 Analyzer features an open sample path that measures methane density in ambient air.
The LI-7700 integrates easily with LI-COR eddy covariance systems without requiring any additional components. Using GPS clocks and the Precision Time Protocol (PTP), methane data are synchronized with wind speed and other measurements with sub-microsecond accuracy. Methane fluxes are computed on the SmartFlux® System at the same time as CO2 and H2O fluxes.
For other applications, the LI-7700 can be ordered with the optional LI-7550 Analyzer Interface Unit, which provides analog, RS-232 serial, and SDM data outputs, as well as other functions.
PT Unitama Analitika Perkasa was established in 1997 and started operating in 1998.
