This air flow meter is very economical. With this air flow meter you can measure wind speed and air temperature. Once you have the right cross section, the air flow meter will show the air flow. The readings can be stored in the device and then transferred to a computer for further analysis. As such, you can take a series of measurements with the air flow meter off-site, then look closely at the data once back at the office. In this way, you save time and maintain a high level of accuracy in readings.
The external impeller, connected by a 1.5 m / 4.9 ft long cable, increases the mobility and flexibility of measurements of wind speed. These air flow meters form a part of the basic equipment of an installation technician for ventilation systems. The useful life of the battery is approx. 50 hours with a current of 300-mA/h. If you wish to take timed measurements over a period of time longer than 2 days, you will need to use a battery pack, or a power adapter.
