With the widespread application of electronic information technology, the interference free coexistence of a large number of electronic products has become an urgent issue, and targeted electromagnetic compatibility (EMC) measures are becoming increasingly important in the laboratory high-frequency resolution electromagnetic radiation monitoring and alarm system. The TC200 field strength monitoring instrument is a compact and durable measuring tool designed specifically for electromagnetic field radiation immunity, workplace electromagnetic radiation monitoring, and vehicle electromagnetic radiation monitoring. It provides large bandwidth, large dynamics, high precision, and sensitivity, while also having excellent isotropy. Provide stable and lasting on-site experience for various testing units and research and development institutions.
