PCE-VA 20 is a multifunction thermometer for testing heating, ventilation and air conditioning or cooling (HVAC) systems. 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
