Relative humidity measuring instrument VA 20-SET-ICA

powertemperatureflow

PCE-VA 20-SET is a air humidity meter with flow hoods for assessing and balancing heating, ventilation and air conditioning or cooling (HVAC) systems. In addition to measuring air flow velocity (i.e., wind speed), this multipurpose air humidity meter measures volume flow, relative humidity (RH), air temperature, dew point temperature and wet-bulb temperature. This combination climate meter 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. Highlights - 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 - Incl. ISO Calibration Certificate Specification Technical Specification Air flow velocity measuring range - 0.2 ... 30 m/s (39.4 ... 5905.5 fpm) Air flow velocity accuracy - 20 m/s: ±(3% of rdg. + 0.3 m/s) Air temperature measuring range - -20 ... 60 °C / -4 ... 140 °F Air temperature accuracy - ±0.6 °C Air temperature resolution - 0.1 °C / °F
