Wool fiber fineness value is measured by the airflow method. When exerting a certain pressure air to a certain amount of mass and volume of sample wool fiber, because the fineness of wool fiber is different, the flow of gas through is different, and by measuring the gas flow, the relevant wool fiber fineness value can be tested.

Wool fiber textile factory wool inspection  

GB/T 11603 Determination of average diameter of wool fiber by airflow method
ISO1136 Determination of average diameter of wool fiber by permeability method
BS3183 Determination of fineness of wool fiber by airflow method
ASTM D1282 Standard test method for average wool fiber diameter of top wool, sliver wool and washed wool by airflow resistance

Wool Fiber Fineness Analysis TesterUsing high-precision and large range of electronic flow sensor, a wide range of wool measurement, up to 12 ~ 50um, can measure ultra-fine wool, you can test most wool in the market, which is the most extensive range instrument for measure of wool fineness that using airflow method in the world.

Only one button is required for testing, finish installing the sample, just press a button, you can quickly to start test, the instrument have USB interface, you can use the included software to statistical and analysis the test result, print the standard test report, you can also save the test report as EXCEL format.
Easy to calibration, fast speed to calibration, after calibration, in non-standard laboratory environment can also achieve 0.2um accuracy.
