  • Calculation of barometric air pressure 

  • Barometric altitude measurement 

  • 8 switchable pressure units 

  • Easy to use; backlit display for use in all lighting conditions 

Small, handy and practical: the testo 511 absolute pressure meter measures absolute pressure and is also suitable for measuring the barometric altitude between two points. 


Product Description

The Testo 511 absolute pressure meter is an ideal instrument to calculate absolute pressure compensation at ducts with a pitot tube. It's +/-1.2 "H20 accurate. It can also calculate barometric pressure and measure altitude. This handy pocket meter is very easy to operate. The 511 has the functionality to switch between 8 pressure units.

| hPa | mbar | Pa | mmH2O | mmHg | inH2O | inHg | psi |

The testo 511 is normally used to measure absolute pressure, e.g. for density compensation in flow measurement in ducts, laboratories and production processes. Other measurement parameters are barometric air pressure (= air pressure at sea level) and altitude above sea level.
  • High-precision absolute pressure measurement with an accuracy of ±3 hPa
  • Suitable for barometric altitude measurements
  • Calculates the barometric air pressure

Advantages of the testo 511 absolute pressure meter

The testo 511 absolute pressure meter is very handy, small and easy to use. It measures the absolute pressure with an accuracy of +/-3 hPa and is ideal for absolute pressure compensation in flow measurements. This is then converted to barometric air pressure by entering the on-site altitude above sea level. You can also use the measuring instrument to measure barometric altitude between two points.
