PCE-VA 20-SET Multifunction HVAC Meter with Flow Hoods
Combination anemometer-hygrometer-thermometer for HVAC system testing, adjusting and balancing (TAB)
PCE-VA 20-SET is a multifunction HVAC meter with flow hoods for testing, assessing and balancing (TAB) heating, ventilation and air conditioning or cooling (HVAC) systems. This combination anemometer-hygrometer-thermometer features a 10 cm / 3.9″ diameter 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
– 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
