The Kanomax Model 6720 TABmaster Airflow Capture Hood provides a complete, lightweight, and easy‑to‑handle solution for HVAC testing, adjusting, and balancing (TAB). It comes with interchangeable hoods to accommodate any duct size, registers, diffusers, or grilles. The full‑color screen can be tilted for optimal viewing at any working height.

The system includes a removable handheld micromanometer with built‑in Bluetooth for wireless operation and data transmission. It displays both airflow direction and velocity, and can store up to 8,000 measurements—with the ability to group multiple readings under a single ID. Data management is supported by two mobile applications: Kanomax TAB Viewer (Android/iOS) and Building Start AirNAB (iOS). The Model 6720 is approved for HERS (Home Energy Rating System) testing and includes a NIST‑traceable calibration certificate.
