Multifunction Air Flow Meter with Capture Hoods PCE-VA 20-SET

PCE-VA 20-SET Multifunction Air Flow Meter with Capture Hoods
Combination anemometer-hygrometer-thermometer for HVAC system balancing

PCE-VA 20-SET is a multifunction air flow meter with capture hoods for assessing and balancing heating, ventilation and air conditioning or cooling (HVAC) systems. In addition to measuring air flow velocity (i.e., wind speed), this multipurpose handheld device measures volume flow, relative humidity (RH), air temperature, dew point temperature and wet-bulb temperature. 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
– Includes 2 x flow hoods (1 x round 210 mm / 8.3″ Ø, 1 x square 346 x 346 mm / 13.6 x 13.6 in)
– 10 cm / 3.9 in Ø fan impeller
– Easy-to-read backlit LCD
– Display hold, average value, maximum value, minimum value, battery-saving automatic power off, low
battery indicator, and metric or imperial unit selection functions
