The PCE-VA 20-SET is a multi-functional hygrometer including flow hoods for assessing and balancing heating, ventilation and air conditioning or cooling (HVAC) installations. This multi-faceted anemometer-thermometer-hygrometer incorporates a 10 cm / 3.9" diam. fan impeller, easy-to-view backlit LCD, and useful functions, e.g. display hold, average val, maximum val, minimum val, auto power-off, low battery indication, and imperial/metric option.

• 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°C / 0.18°F
• 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)
• incl. ISO Calibration Certificate
