The Fabric Anti-Electromagnetic Radiation Performance Tester is a precision instrument designed to measure the electromagnetic shielding effectiveness of various materials, including textiles, plastic sheets, metal foils, coatings, platings, conductive films, metal meshes, conductive glasses, and conductive medium plates. The tester employs the coaxial test method, providing high accuracy and reliable results for full-frequency, list, and point-frequency measurements.
Application
This tester is widely used for:
Evaluating shielding performance of electromagnetic shielding fabrics for garments and protective materials.
Testing coatings, conductive films, and metal meshes for electronics, aerospace, and automotive applications.
Assessing absorptive and reflective properties of planar materials against electromagnetic waves.
Research and development of EMI/EMC compliant textiles and composite materials.
Quality control in textile manufacturing and material certification labs.
