Hummer Anemometer

The Wallis & Gill Hummer Black Anemometer is a robust, high-precision wind sensor designed for continuous operation in demanding marine and environmental conditions.

The 2026 version introduces a lighter and more compact design, improved ceramic bearings, increased sensitivity to light winds, and a modular architecture that allows the wind sensor head to be separated from the main electronics, simplifying installation and maintenance.

Field-proven in real-world conditions, the AK3 successfully completed five months of operation aboard a high-sea fishing vessel in the South Atlantic, demonstrating reliability and durability under extreme weather and salt exposure.
