1.Real-time measurement and alarm function:The device continuously monitors and displays the measured values of radiation, electric field strength and magnetic field strength and their corresponding units. And evaluates the danger level according to the alarm threshold set for each measured value 2.Flexible radiation unit settings:The device allows users to select the radiation measurement unit. Available units include μs v/h, /h, mR/h, , CPM, etc 3.Alarm record display function:The alarm record page displays the alarm records in sequence, with the serial number increasing from the oldest to the latest. Each record contains the type of data that triggered the alarm (for example, radiation, electric field strength, magnetic field strength) and the specific date and time when the alarm was triggered 4.Various alarm modes:This area is highlighted, indicating that the alarm mode setting is entered and the corresponding setting content is displayed.
