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

The thermo hygrometer has a CO² measuring range of 0 … 9999 ppm. In addition to the carbon dioxide measurement, the thermo hygrometer also has a carbon monoxide (CO) sensor with a measuring range of 0 … 1000 ppm and a temperature and humidity sensor.

• Carbon monoxide (CO): 0 … 1000 ppm
• Carbon dioxide (CO²): 0 … 9999 ppm
• Temperature: 0 … 50 °C / 32 … 122 °F
• Humidity: 0 … 100% RH
• Data memory for 5000 measuring points
• Data export CSV
• Power supply: rechargeable battery

PCE-VA 20 is a multifunction hygrometer for assessing wind, weather, indoor / outdoor environmental climate conditions as well as 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.
