The DBM 620 Air Flow Meter is a versatile electronic instrument used primarily for taking precise air volume readings from air vents. Its redesigned features optimize air balancing tasks, making it an efficient tool for measuring airflow in various HVAC applications. The device provides accurate readings for air velocity, pressure, and volume, ensuring precise airflow management in commercial and industrial environments.

The DBM 620 Air Flow Meter is the first air balancing instrument to include the Air Changes per Hour (ACPH) metric, offering a unique and valuable feature for accurately assessing airflow efficiency in HVAC systems.
Easily switch between 5 hood configurations. Quickly adapt to different measurement setups for efficient airflow assessments.
SmartKap App. Effortlessly view and export data, simplifying analysis and reporting for enhanced efficiency.
Autonomous Micromanometer Function. Can be used independently with a Pitot tube attachment for precise pressure measurements in airflow applications.
Compact & Lightweight. Smaller and lighter than previous models, offering enhanced portability and ease of use without sacrificing performance.
Extendable Tripod. Eliminates the need for ladders in most environments, making measurements easier and safer in high or hard-to-reach areas.
