The LI-7500DS features miniaturized electronics, lower power requirements, and a lower price while delivering the dependability and improved optical design of the legacy LI-7500RS model in a simpler, easier to use instrument. The open path design is ideal for sites with infrequent rain, fog, and snow events.
The LI-7200RS features an enclosed optical path with high-precision, temperature-controlled optical filters that provide dependable gas density measurements, including dry mole fraction, in the most challenging outdoor environments. The LI-7200RS is best suited for environments that have frequent rain, fog, or snow events and very low CO2 flux rates.
The LI-7700 features an open-path design that reduces power consumption and eliminates problems associated with pumps, tubing sorption, and tubing delays. The LI-7700 easily integrates with LI-COR eddy covariance systems, making methane flux measurements easier than ever.
