3-In-1 EMF Detector: The EMF detector is a precision handheld electronic device with a built-in sensor that captures EF, MF, and RF radiation signals.The EMF reader is equipped with a high-precision, wide-band RF sensor and a triaxial magnetic field sensor, enabling fast and accurate measurement of EF (Electric Field), MF (Magnetic Field), and RF (Radio Frequency) values.High Practicality: The EMF detector features a 2.4-inch TFT color display for intuitive visualization of measurement data.It shows real-time values, maximum values, and average values simultaneously.Additionally, it dynamically presents measurement data trends via line charts, providing clear visualization of value fluctuations.Alert Modes: The EMF detector supports four alert modes: audible alarm, LED indicator, vibration, and on-screen display.When measured values exceed the threshold, the corresponding numerical values and curves will change color.An overload alarm is triggered when electromagnetic radiation exceeds the measurable range.The device also continuously monitors battery status and provides low-power alerts.Versatile Applications: The EMF detector is widely applicable for both daily and professional use.It can measure radiation levels in living spaces, offices, computer rooms, communication base stations, and other environments to help identify and relocate excessive radiation sources.It tests radiation emissions from electronic devices like mobile phones, routers, and microwave ovens, providing precise data for electromagnetic safety management.Precautions: The EMF detector must be held in hand during measurement, as its calibration is based on handheld operation. When approaching the detection target, maintain a steady position and avoid rapid movement, since the instrument requires response time for accurate readings.
