Testo rpm measuring instruments, Tachometer, Vane anemometer and air velocity meters

Wind speed can be precisely measured with high accuracy and precision anemometers. Compact vane and surface vane types are available to suit diverse requirements. For operating the vane anemometer, the device should be placed with its axis parallel to the wind direction. Digital tachometers that operate without direct contact to the rotating device are also a requirement for several high speed applications where the speed sensing should be performed remotely. Air velocity meters are multifunctional devices used in various measurement applications. These are used to measure air velocity and temperature in digital formats, and the measured results are used later in statistical calculations.
