Our Advantages
Our Biggest Advantage is our specialization in Shielding Effectiveness Measurments
Beijing Daze Testing Department is a professional organization specializing in shielding effectiveness testing. Established in 2015, there are currently 7 employees, including 2 management personnel and 5 testing personnel. All employees have undergone job training and assessment. We currently have domestically produced testing equipment such as a large shielding effectiveness testing system, a small shielding effectiveness testing system, a window method and flange coaxial testing device, and a spectrum analyzer. At present, the laboratory conducts on-site shielding effectiveness testing services for shielding rooms, anechoic chambers, nuclear magnetic resonance rooms, shielding tents, shielding cabinets, electronic shielding shelters, and various shielding materials. Here are some of the customers we have served.
