With the dew point thermometer it is possible to measure climate conditions such as temperature and relative humidity, as well as determining surface temperature of objects simultaneously by using the included external temperature sensor or using an infrared measurement. The dew point thermometer offers features such as average value, maximum, minimum, and hold functions at a reasonable price.

• Internal probe
• Temperature: -20°C … 60°C / -4 … 140°F
• Relative humidity: 10 … 90% r.H.
• Temperature of global: -22°C … 60°C / -8 … 140°F
• Humidity: -68°C … 60°C / -90 … 140°F
• Dew point temperature: depending on the sensor

• External probe
• Temperature: -50° C … 500° C / -58 … 932°F

PCE-VA 20 is a Dewpoint Meter 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
