Replaces the Licor  LI-7500 in Campbell OPEC (Open Path Eddy Covariance) systems

The EC150 is an in-situ open path gas analyser specifically designed for eddy-covariance flux measurements. It simultaneously measures absolute carbon dioxide, water vapour densities, air temperature and barometric pressure. With the optional CSAT3G Sonic Anemometer head, the EC150 also provides 3D wind speed and sonic air temperature measurements.

The device is specifically designed to match with the CSAT3A to co-locate the measurement volume of the gas analyser and the sonic and also to minimise air flow disruption casued by the instrumentation. The EC150 also shares electronics with the CSAT3A to reduce system complexity and cost but also to provide syncronisation of the measurements of the two sensors before they reach the data logger reducing logger processing.
