for ecosystem net exchange (NEE) Transparent automatic air chamber for measurement(optional)
eosAC-LT/LOair chamber can be used to measure the net exchange capacity of the surface ecosystem.NEEresearch.eosAC-LT/LOcan be replaced in the field environment to minimize data loss caused by instrument shutdown. The air chamber has two auxiliary interfaces, which can be accessed with additional sensors (e. g.PAR, soil temperature, soil moisture, etc.) and other environmental data of the measurement location; the built-in fan can effectively promote the mixing of gases. Users can also choose air chambers with transparent or opaque side walls according to their needs.
