The new X-LAS MkII Scintillometer provides continuous measurements of sensible heat fluxes over path lengths from 1 km up to 12 km. The measurement process is very straight forward and yields fast results. Since limited power is required, in most cases a simple solar-charged battery is sufficient.

The X-LAS MkII receiver has internal digital processing unit automatically computes all relevant parameters, such as Cn2 and the sensible heat flux. Real-time data is available on the display so you will know the status of your experiment in seconds. The built-in data logger stores several months of measurements and results.

A digital interface allows remote real-time display and full control over the instrument operational settings. Analogue outputs are also available enabling connection of the instrument to virtually any data acquisition system. This allows for easy integration into new or existing measurement networks.

Carrying instruments around for field deployment is already labour intensive enough, without having to think about laptops, interface cables and software. The X-LAS MkII can be installed and configured using its built-in display and key-pad without the need for any extra equipment, and features a carbon fibre housing for easier transport. The carbon fibre also ensures a very stiff and temperature stable enclosure for the optics, ensuring accurate, long term data.

The scintillometer on its own measures changes in refractive index of the atmosphere, Cn2, but with the optional meteorological sensor kit it can calculate sensible heat flux. This kit consists of wind speed, temperature and pressure sensors and plugs directly into the X-LAS MkII receiver.

The EVATION® software suite is included as standard to view real-time data numerically and graphically and provides advanced data post-processing.
