【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.

Color Backlit Alarm:When a reading exceeds a safe level (250 V/m or 5 μT/50 mG or 50 mW/m²), the screen turns red to notify the user, but does not display frequency-specific information. Green, orange and red screens indicate low, medium and high radiation levels respectively

Mute Setting:There's a mute setting to avoid scaring ghosts away. Additionally, the device will auto-off after fifteen minutes of no operation

Easy to Use:Operate with one hand and move or make field.When using an electromagnetic radiation detector for measurement, try to hold the lower part of the measuring device as much as possible to avoid the influence of hands

User Friendly:The EMF reader also provides a maximum value, "HOLD" freezes the screen to observe the reading, and a long press on the power button turns off the backlight to conserve power.

TIPS One:Determine the known sources of electromagnetic radiation and relocate them as far away from the child's room or in a common area of the house as possible

TIPS Two:When checking electromagnetic radiation, the strength of the signal and distance from the source will affect the measurement results. Keeping a certain distance from the radiation source will show a lower value on the EMF tester, indicating greater safety
