DESCRIPTION
PCE-VA 20 Multifunction Air Velocity Meter
Combination anemometer-hygrometer-thermometer for assessing wind, weather, indoor / outdoor environmental climate conditions

PCE-VA 20 is a multifunction air velocity meter for assessing wind, weather, indoor / outdoor environmental climate conditions as well as for testing 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.
HIGHLIGHTS
- 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
- 10 cm / 3.9" 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
