The airflow meter VA 11 is an extensively used measuring instrument. The airflow meter provides the opportunity to determine air speeds, air temperature and infrared temperature. The backlit LCD allows comfortable readings and facilitates use in dimly lit areas. To mount the windmill it has a thread on the back. Here it is possible to mount the wind meter on a thread. Thanks to the fast response time of the device, real-time measurement is possible without problems. The large display provides an accurate overview of the measured values and can optionally be backlit, which makes the wind meter useful even in low light conditions. Immediately after the impeller has been connected, the measurement can be started and measured values are immediately displayed on the display. Even if a specific temperature is to be measured at special measuring spots, this is possible by means of simple keystroke. The light laser serves as an orientation point. The measurement of the ambient temperature is then automatically deactivated. In addition to the wind speed, the device can also measure the airflow and the air temperature and is thus a very versatile measuring device, which can be used in different areas.
