Remote Air Velocity Sensor

The Remote AV Sensor is the ideal solution for unidirectional flow and ventilation monitoring in cleanroom environments and for HVAC applications.

The Remote AV Sensor has a highly accurate sensor for measurement of low air velocity and is most suitable for cleanroom and controlled environment device monitoring such as isolators, cabinets and biological safety cabinets. With its excellent high accuracy thin film sensor the Remote AV Sensor offers great accuracy at low velocities down to 0.15m/s (30ft/min).

Only one CAT 5/6 cable is required for power and communications.
