Description
PCE-VA 20-SET Humidity Detector with Air Flow Hoods
Combination anemometer-hygrometer-thermometer for HVAC system balancing
PCE-VA 20-SET is a humidity detector with air flow hoods for assessing and balancing 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
- Includes 2 x capture hoods (1 x round 210 mm / 8.3 in 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
