Real-time electromagnetic field testing and monitoring - Function: This device tests electric field radiation and magnetic field emissions to achieve optimal test results. It is used to assess electromagnetic radiation conditions indoors and outdoors and to learn from them. - Real-time monitoring and alarms: Electromagnetic radiation monitors react quickly to radiation and provide timely alarms in high-risk environments. The instrument is highly flexible and can measure environmental backgrounds. Readings update in real time. - Portability and data integrity: Electromagnetic radiation detectors are small and portable. Data is stored permanently even during power outages. Beginners, seniors, and advanced users can operate it easily. The large LCD screen enables easy and quick reading of real-time values. - Applications and suitability: Widely used by individuals as protection monitors and for radioactive indications. Suitable for workers in the following areas: electromagnetic power plants, accelerators, iron and steel industries, chemical industries, isotope applications, nondestructive industrial testing and gamma defect detection, cobalt source processing, gamma radiation laboratories, and environments around cores.
