AVDTMR Airflow & Temperature Transmitter - Duct, LCD, Rly

The Air Flow and Velocity Transmitter series is intended for use in commercial environments. It is designed with a duct mount probe and adjustable collar suitable for round or rectangular ducts. The transmitter provides separate readings for air velocity and temperature. It comes with three measurement ranges in a single device (0–2 m/s, 0–10 m/s, 0–20 m/s). This model includes an Metric LCD Display and an adjustable relay.
