SwemaAir 5 is an anemometer for air velocity, air flow and temperature. The instrument has a built-in barometer. Together with the temperature sensor SwemaAir 5 compensates for the air density.
The instrument suits a wide range of applications, such as air flow measurements in ducts and over grilles, checking air leakage at windows and measuring air velocity in fume cupboards.
Air flow is calculated from the air velocity and the cross-section area using EN 16211 method ID 2. Max, min and average value is displayed.

Measurement uncertainty at 23°C
±3% read value, min ±0,04m/s, min ±8 fpm
Temperature: ±0,3°C, ±0,5°F
Barometer: ±3 hPa
Measurement uncertainty at 10...30°C
±5%, min ±0,05 m/s, min 10fpm
Barometer: ±3,5 hPa, ±0,1 inHg
Measurement uncertainty at -20...80°C
Temperature: ±1,0°C, ±1,8°F
Uncertainty according to GUM (JCGM 100ː2008) using a coverage factor of 2, which for a normal distribution corresponds to a probability of 95%. It is important to correct the measurement values with the corrections stated in the calibration certificate to obtain the above uncertainties.
