Product Description
The PVF module reads pressure, velocity and airflow. Every pressure module is calibrated
against NIST standards and comes with a certificate of calibration. By using a wrist
reporter with the PVF module, a user can see real-time results wirelessly on the wrist.
ROOM TO ROOM PRESSURES : For room-to-room pressure applications, a user can place
up to 10 pressure modules and monitor all 10 concurrently while making adjustments.
VELOCITY & DUCT READINGS : The pressure module can also be used with a capture
hood to measure velocity and flow applications. This allows the user to monitor multiple
diffuser air flow relationships.
