Tip two: Use an EMF device to evaluate radiation risks and make appropriate decisions. Move known radiation sources far away from children's or community rooms.
Tip three: operate with one hand and move or make a field. Try to hold the lower part of the gauge when measuring to avoid the influence of your hand.
Tip one: with a certain distance from the radiation source, the EMF metre displays low values, which is safer.
Note: The data for measuring the electric field of the antenna may not be captured if the distance is too large, if the antenna is at a safe distance or if it does not work.
Mute: Mute: The EMF metre can be muted to avoid ghost interference, and automatically shuts off after fifteen minutes of silence.
Important: Please do not compare our electromagnetic field radiation detector with other products as each product has different measurement standards. –
Illuminated display. The EMF detector has an illuminated LCD display that helps detect ghosts at night; in addition, the backlight of the screen can be turned off by long pressing the power button in sleep mode.
Detects all three types of EMF pollution: AC magnetic, AC electric and RF/microwave. (Specific frequency data is not shown).
Colour illuminated alarm: The three-colour indicator bar shows green, yellow and red; an automatic alarm is triggered when the safe value is exceeded (250 V/m or 5 μT/50 mG or 50 mW/m²).
