SFL-1 Air Volume Instrument adopts the pitot principle. It can measure automatically the multi-spots to the wind pressure in many times. Its average amount of wind is correct, fast and simple. It is widely used in mensurating the in-out wind of the air-conditioning and the purification technologie so that the systems can be administered and their parameters are adjusted automatically. It adopts the overseas vanguard technologies of the similar products. Every product will be proofreaded strictly in testing by the multi-spot amount of wind meter before it leaves our factory, in order to providing the reliable guarantee for the user to mensurate amount of wind straightway. 1、DC supply up to 30 h once, rechargeable 2、Adjustable base-supporter with wheels, replaces human supporting effort, up to 3 m supporting height, making wind volume measurement more convenient. (Optional to purchase) 3、Being able to store up to 99 measurement data. All data readily readable, deletable, printable and recordable 4、Range of Measurement: Air volume 150m3/h – 3,500 m3/h Self-resistance ≤ 5 Pa Precision ≤ 5% FS Basic Configuration: ● Air Volume Instrument main body (Foundation bed) ● Air Volume Instrument cover 570×570(mm); 830×830 (mm) Selectable Accessories: ● Adjustable supporter ● External printer
