TESTO 511 Absolute Pressure Meter 300-1200hPa/mbar

The TESTO 511 Absolute Pressure Meter is a high-precision handheld instrument designed for the measurement of absolute pressure. It is commonly employed for critical tasks such as density compensation in flow measurement within ducts, laboratories, and various production processes. Beyond absolute pressure, the device is also capable of measuring barometric air pressure (the air pressure at sea level) and calculating altitude above sea level, making it an exceptionally versatile tool for field technicians and engineers.

Engineered for accuracy, the TESTO 511 offers absolute pressure measurements with a precision of ±3hPa. This level of reliability makes it perfectly suitable for conducting barometric altitude measurements between two distinct points, a common requirement in surveying and installation work. The unit automatically calculates the barometric air pressure, streamlining data acquisition and reducing the potential for manual error.

Key Features & Functionality

The meter boasts a clear, backlit display that ensures readability in all lighting conditions, from dimly lit industrial environments to bright outdoor settings. It supports a comprehensive selection of pressure units, including kPa, mbar, Pa, mm H₂O, mmHg, inch H₂O, inch Hg, psi, as well as altitude units in metres and feet, providing unparalleled flexibility for international standards and user preference.

Included Accessories & Specifications

Supplied complete for immediate use, the package includes a protective cap to safeguard the sensor, a practical wrist strap, a belt holder for hands-free portability, and two AAA batteries. A calibration protocol is also provided, confirming the instrument's accuracy out of the box. The device operates effectively within a temperature range of 0°C to 50°C and covers a pressure measuring range from 300hPa to 1200hPa.

Compact and robust, the TESTO 511 is an indispensable instrument in
