Hot Wire Anemometer AVM 7140 is a thermal anemometer designed for the measurement of low air velocity. It has RS 232 PC serial interface and can be used to measure airflow for different functions such as m/s, km/h, ft/min, knots, mile/h. The anemometer is portable and provides accurate reading at fast speed with easy to read digits and the expediency of a remote explore separately. The slim probe can be used for grillers and diffusers. It has an amalgamation of hot wire and standard thermostat to provide rapid and precise measurements even at low air velocity value. The unit has a microprocessor circuit that provides accurate results for the special functions and features. The large sized LCD can perform dual operations such as meter display and read the air velocity and temperature at the same time.
