DESCRIPTION
Condition Monitaring PCE-VA 20
Combination anemometer-hygrometer-thermometer for assessing wind, weather, indoor / Outdoor environmental climate conditions

PCE-VA 20 is a condition monitoring 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 temperature, this multipurpose handheld device measures dew point temperature, wet-bulb temperature, air flow velocity (i.e., wind speed), volume flow and relative humidity (RH). 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
