Heavy-duty wind sensor, designed for working under extreme cold weather conditions (until -25°C with ice and snow). The body of the sensor, is made of a special anti-shock material which protects the electronic parts against dirt and humidity and the rotor is mounted on special low torque bearings to ensure exceptional performances in terms of reliability, precision and measurement accuracy.

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.
