LAS MkII Scintillometer

Easy to use and with real-time data directly from the display. The LAS MkII Scintillometer contains a built in GPS, data logger and data processing to enable stand-alone operation.

The LAS MkII measures atmospheric turbulence and can derive sensible heat fluxes over distances from 100 m to 4.5 km.


The LAS MkII Scintillometer provides continuous measurements of sensible heat fluxes over path lengths from 100 m up to 4.5 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 scintillometer can be combined with a meteorological sensor kit to calculate wind speed, temperature and pressure sensors and plugs directly into the LAS MkII receiver.
