We provide calibration according to MEASNET guide lines for wind measurement sensors. Calibration is recommended to be done before and after measurement campaign. For long term measurements recommended calibration interval is two years.


Sodar and lidar units are sent to calibration at the manufacturers premises. For sodar and lidar units we provide also comparison against mast measurements.

Installation, maintenance and operation

Maintenance service includes also automatic data collection, data follow up and quality checks.

Power supply

We sell, rent and service mobile power units to provide electricity to wind measurement systems in places where grid is not available.


Typically power unit includes solar panels and diesel generator that has automatic control and remote monitoring.


Units can be constructed in trailer or small sea container. Power output ranges from 100W to 2kW continuous nominal power with 12/24/48Vdc or 230Vac input. The unit will be prepared according to the electricity requirements of the measurement system.
