WindObserver 75

The WindObserver 75 has been developed for measuring higher wind speeds in extreme weather environments featuring 150 Watts of electrical heating power in the anemometer head.

This anemometer has been designed to remain ice-free in most freezing weather conditions.

The sensor provides data via RS422/RS485 bidirectional link, which allows several units to be networked together and data logged on demand.


Product Description
