PCE-VA 20-SET Air Humidity Meter with Capture Hoods
Combination anemometer-hygrometer-thermometer for HVAC system balancing
PCE-VA 20-SET is a air humidity 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 air humidity meter measures volume flow, relative humidity (RH), air temperature, dew point temperature and wet-bulb temperature. This air humidity meter 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
