Product Description
The Pressure / Velocity / Flow (PVF) Module is a wireless environmental measurement sensor designed to capture pressure, air velocity, and airflow data with high accuracy. Each PVF module is NIST-traceable calibrated and supplied with a certificate of calibration for regulatory and quality assurance requirements.
When paired with a Wrist Reporter, users can view real-time measurement data wirelessly on the wrist, improving efficiency during HVAC testing, balancing, and diagnostics.
Room-to-Room Pressure Monitoring
For room-to-room pressure applications, users can deploy up to ten PVF modules simultaneously and monitor all readings in real time while making airflow and pressure adjustments.
This capability allows fast identification of pressure relationships between spaces such as cleanrooms, isolation rooms, and controlled environments.
Velocity & Duct Measurement
The PVF module can be used with capture hoods and airflow probes to measure air velocity and volumetric flow, supporting multi-diffuser airflow comparison and system balancing.
This allows users to monitor airflow relationships across multiple diffusers at the same time for improved HVAC performance verification.
