The Testo 511 Absolute Pressure Meter is a compact measuring instrument designed for HVAC engineers, ventilation technicians and commissioning professionals who need accurate absolute pressure readings for airflow calculations and environmental monitoring.
Built for applications such as duct testing, Pitot tube measurements and barometric pressure checks, it delivers reliable results with ±3 hPa accuracy. By entering site altitude, the instrument converts absolute pressure into barometric air pressure, making it ideal for density compensation in airflow measurements and system diagnostics across HVAC and industrial environments.
How does the Testo 511 stand out in everyday use?
The Testo 511 combines precision with simplicity in a pocket-sized design. It supports multiple pressure units and allows barometric altitude measurement between two points, making it a versatile tool for on-site testing and environmental assessments.
With long battery life, lightweight construction and included accessories such as a protective cap and belt holder, it’s built for convenient, reliable use during routine HVAC measurements and commissioning tasks.
