E+E HVAC Air Velocity Probe

The EE671 is a compact HVAC air velocity probe designed for precise airflow monitoring in ventilation systems, ducts, and industrial air handling applications. Integrated with Microclimates EnvOS®, the probe enables real-time air velocity monitoring, system performance tracking, alerts, and historical reporting for environmental control and HVAC optimization. Using a hot-film anemometer sensing element, it provides stable, high-accuracy airflow measurement with long-term reliability even in polluted or demanding air environments.
