In HVAC system diagnostics and commissioning, accurate airflow measurement is essential, not just for performance validation, but also for occupant comfort, energy efficiency, and regulatory compliance. That’s where the DBM 620 balometer by Sauermann comes in: a reliable, portable, and connected solution for measuring air volume flow at diffusers, grilles, and ventilation outlets.
Engineered for field efficiency
The DBM 620 is designed with the field technician in mind. Its lightweight, modular construction features interchangeable hoods to suit various terminal sizes, making it adaptable to a wide range of on-site conditions. The large backlit digital display offers clear readings even in low-light environments, while the intuitive interface ensures fast and accurate setup.
Measurement accuracy, certified
At the heart of the DBM 620 is a high-precision sensor that guarantees reliable and repeatable measurements of air volume flow, both supply and return, from 40 to 4,000 m³/h. It enables professionals to conduct air balancing with confidence, ensuring that airflow rates meet system specifications and comfort standards.
Smart data handling
The DBM 620 integrates seamlessly with the Si-HVACR Measurement mobile app via Bluetooth® connectivity, allowing users to:
