Overview

The Nikos microwave radiation protective clothing shielding effectiveness testing system is used for GB 23463-2025 microwave radiation protective clothing clothing shielding effectiveness testing, supporting the collection and SE calculation of electric field strength at measurement points such as the head, chest, and lower abdomen of the human body model.

Product Details

Product Overview

Nikos Microwave Radiation Protective Clothing Shielding Efficiency Testing SystemTargeting the shielding effectiveness test of ready to wear clothing in GB 23463-2025 "Protective Clothing for Microwave Radiation Protection". The system is located in a shielded room and compares the electric field strength E0/E1 between the non wearing and wearing protective clothing using a microwave signal source, transmitting antenna, RF cable, receiving end, and human body model. The shielding effectiveness is calculated based on SE=20lg (E0/E1).

This system is suitable for reflective microwave radiation protective clothing, as well as absorbing microwave radiation protective clothing that uses absorbing materials to attenuate microwave radiation. Standardized testing configurations can be carried out around the shielding effectiveness of ready to wear clothing, testing frequency points, testing locations, environmental conditions, data recording, and reporting fields.
