This air flow meter is very economical. With this air flow meter you can measure wind speed and air temperature. Once you have the right cross section, the air flow meter will show the air flow. All the test instruments come manufacturer calibrated. ISO certification can be made as an option.

• Speed measurement up to 45 m/s or 100 mph
• Wind speed: 0.01 m/s, accuracy ±3% ±0.1
• Air temperature: 0.2°C / 32.4°F, accuracy ±1°C / 33.8°F
• Air flow: 0.001 to 100, accuracy calculated from the wind speed and surface

PCE-VA 20 is a multifunction air flow meter for assessing wind, weather, indoor / outdoor environmental climate conditions as well as for testing heating, ventilation and air conditioning or cooling (HVAC) systems. This combination anemometer-hygrometer-thermometer features a 10 cm / 3.9" Ø fan impeller, easy-to-read backlit LCD, and functions such as display hold, average value, maximum value, minimum value, battery-saving automatic power off, low-battery indicator, and metric or imperial unit selection.

• Measures air flow velocity, volume flow, relative humidity, air temperature, dew  point temperature and wet-bulb temperature
• Air flow velocity range: 0.2 … 30 m/s (39.4 … 5905.5 fpm)
• Accuracy: ±(1.5% of measured value + 0.3 m/s) when less than 20 m/s, ±(3% of  measured value + 0.3 m/s) when more than 20 m/s
• Resolution: 0.1

PCE-HVAC 2 is a high-velocity multifunction air flow meter with a pitot tube. This portable air flow meter can be used to determine air speed, air pressure, air flow, differential pressure and ambient temperature. The pitot tube allows access through tiny openings to take measurements in small pipe systems and other confined spaces.

• Measures air velocities up to 80 m/s / 262 ft/s, 2.24 … 178.66 MPH  
• Zero, minimum, maximum, average, record and hold functions
• Stores to memory up to 99 measurement values per parameter

The air flow meter is compatible with and can be mounted on to a wide variety of available measuring equipment. The sensor will detect even the minutest movements of air and the results are then output in analogue form. With heating.

• Output signal: 0 … 10V
• Operating voltage: 12 … 36V DC
• Measurement reading range: 0.5 m/s … 50 m/s (1.1 … 111.8 mph)
