testo 511 - Absolute Pressure Meter

testo 511
The testo 511 is a high-precision absolute pressure meter, ideal for density compensation in flow measurements, barometric air pressure calculations, and altitude determination. With an accuracy of ±3 hPa, it ensures reliable pressure readings for use in ducts, laboratories, and production environments. The device can also measure barometric altitude between two points by adjusting for on-site elevation.
  • High Precision Absolute Pressure Measurement - with ±3 hPa accuracy.
  • Barometric Air Pressure - converted by entering on-site altitude above sea level.
  • Barometric Altitude - between two points for environmental monitoring.
  • Versatile & Easy to Use - features eight selectable pressure units.

Overview

The testo 511 is a compact and highly accurate absolute pressure meter, designed for precise pressure measurement and altitude determination in various applications. With an accuracy of ±3 hPa, it is ideal for density compensation in flow measurements, barometric air pressure calculations, and altitude measurement in laboratories, production environments, and HVAC systems.

Reliable Absolute Pressure & Barometric Calculations

The testo 511 measures absolute pressure and can convert it to barometric air pressure by entering the on-site altitude above sea level. This makes it a valuable tool for monitoring environmental conditions, ensuring accurate pressure compensation, and performing barometric altitude measurements between two points.

Compact, User-Friendly & Versatile

Designed for ease of use, the testo 511 features eight selectable pressure units, allowing flexibility for different measurement needs. Its lightweight, handheld design makes it perfect for field use, and the simple operation ensures quick and efficient measurements.

Durable & Complete with Accessories

The meter comes with a protection cap, wrist strap, belt holder, and calibration protocol, providing everything needed for professional and reliable pressure measurement. Whether for HVAC applications, laboratory use, or industrial processes, the testo 511 is a practical and precise solution.
