通气阻力及压力差测试仪

产品介绍：

通气阻力及压力差测试仪-用来对通气阻力及压力差的测定，也可用来测定其它纺织材料的气体交换压力差。也可用于厂、劳动防护用品检验机构对产品进行相关的检测和检验。

The mask ventilation resistance and pressure difference tester is used to measure the ventilation resistance and pressure difference of the mask, and also to measure the gas exchange pressure difference of other textile materials. It can also be used for the inspection and inspection of mask products by mask manufacturers and labor protection equipment inspection organizations.

测试原理：

通过气体流量计设定气流的输出，使该气流经过一定面积的测试样品，通过压力传感器检测当前压力并计算压力差

Set the output of the air flow through the gas flowmeter, make the air flow pass through a certain area of test sample, detect the current pressure through the pressure sensor and calculate the pressure difference
