HVAC 2是高速多功能空氣流動計，可用於測量空氣速度、氣壓、氣流、壓差及環境溫度，可利用膠喉配件進入小管道系統和其他狹窄空間進行測量，最高可測量高達每秒80米（m / s）的空氣流速，設有記錄功能，並最多可儲存99個數值，可經由USB讀取記錄。風速計還具有背光顯示屏，可在低光照條件下使用。 HVAC 2底部有一個螺紋，可以安裝在腳架上進行固定測試。
HVAC 2 is a high-velocity multifunction airflow meter with a pitot tube. This portable airflow meter can be used to determine air speed, air pressure, air flow, differential pressure and ambient temperature. The pitot tube allows access through tiny openings to take measurements in small pipe systems and other confined spaces.
- Measures air velocities up to 80 meters per second (m / s)
- Zero, minimum, maximum, average, record and hold functions
- Stores to memory up to 99 measurement values per parameter
Stored measurement values can be called or read out later on the device itself or on the computer. The transfer to a computer works easily via a USB interface. A real-time measurement can also be carried out via this interface. When a USB connection is established, the measured values are displayed on the computer screen using the downloadable PC-compatible software. In addition to an ergonomic design, the anemometer boasts a backlit display that enables use in low-light conditions. The HVAC 2 has a thread on the bottom, so the device can be mounted on a tripod. The measuring hoses are inserted at the top of the device allowing for connection to the pitot tube.
