[0002] Due to the needs of the workplace, people working in electromagnetic radiation pollution source areas need to wear electromagnetic shielding protective clothing to prevent electromagnetic radiation from causing harm to the human body. There is a big difference between the finished electromagnetic radiation protective clothing and the electromagnetic shielding materials. It depends on the shielding performance of the material itself and the closed structure to play the due shielding role. Therefore, the electromagnetic shielding efficiency of the manufacturing material cannot represent the electromagnetic shielding efficiency of the finished product. It is necessary to conduct an overall shielding efficiency test on the finished electromagnetic radiation protective clothing.

However, some electromagnetic protective clothing relies on the conductive layer on the surface of the material to shield electromagnetic radiation, and the humidity in the air will change the conductivity of the material surface and change the shielding effect of the electromagnetic protective clothing. The device cannot test the shielding effect of the electromagnetic protective clothing when the humidity changes. Utility Model Content
