Anemometer with alarm beacons and buzzer, commanded by 2 adjustable thesholds. The rotor doesn't generate any perturbation in the surrounding air ow in such a way as to preserve the excellent accuracy of the instrument. Supplied with fasteners (magnets and anges) and supply cable 10m long. The employment of magnetic sensors, allows the access of the wind speed signal inside the anemometer without compromising its waterproof features.

Anemometers can be handheld instruments and are used for air velocity measurements using air velocity sensors. Air velocity flow sensors can be inserted into a duct or pipe through an access hole to measure air velocity. In other instances a capture hood is used to measure volumetric flow from a grill or exhaust diffuser. Air velocity or volume measurements can often be used with engineering handbook data or design information to reveal proper or improper performance of an airflow system.

Two types of air velocity flow sensors are the insertion probes and balometers or flow hoods. Insertion probes go directly into a duct to gauge the effectiveness of ventilation by measuring air velocity. Flow hoods and balometers measure air volume flow at the air supply or exhaust outlets.
