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 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.
