測量例
由樣品產生的壓力損失是通過半導體差壓計在10秒內透過一種機制進行測量的，該機制透過氣缸的活塞運動將恆定的空氣流發送到樣品，將樣品排放並吸入大氣中，並測量樣品的氣流阻力R. 顯示在數字面板儀表上。
單位：KPa·秒/米
P =帕斯卡壓力
R =阻力值（排氣和進氣的平均值=通風阻力值）
t =時間
v =當前4cc /秒（恆定）
The KES-F8 has been designed to measure the permeability of a sample accurately and promptly. It is applicable to a broad range of samples, from those with high permeability such as a piece of gauze, to those with low permeability, such as a waterproof fabric with moisture permeability.
The sample can be placed and measured easily; since the reading is displayed on the digital panel meter, no reading error occurs between different operators. The resolution of pressure measurement is 2 Pa, assuring high precision.
Feature
KES-F8 sends air at a constant flow rate to the sample by the reciprocal movement of its plunger and cylinder, then discharges the air to the atmosphere through the sample.
The pressure loss due to the sample (at a constant flow rate of (V) 4cc/cm2/sec. for standard measurement) is measured using a semiconductor type differential pressure gauge. The permeating resistance \"R\" of the sample is directly measured, and then displayed on the digital panel meter.
R = kpa s/m
The pressure loss is averaged over three seconds for each half cycle. The averages for the two half cycles are further averaged to increase the measurement accuracy.
Each cycle of the standard measurement is completed within 10 seconds.
