Features: , lightweight and portable, with a built-in high-accuracy chip, it is practical and to use. With a , clear-definition color screen and , colorful font design, it can cope with and bright environments to give you a more comfortable experience.Three parameters are detected simultaneously, fast detection of RF intensity, electric field intensity, and magnetic field intensity, and the data are displayed at the same interface, and it will indicate whether the three data the criteria.Equipped with the current radiation level grading function, 3 different colors correspond to different current radiation levels, allowing for a more accurate and graphical understanding of the current environment.There is a sound alarm function, where a buzzer sounds an alarm when data is detected exceeding the standard, and there is a mute button to turn off the sound.Multifunction design, with lock screen (data lock) function, supports the display of maximum value and average value. Multi-scene applications, this product can be widely used in kitchens, high voltage equipment, homes, offices, factories, etc.Specifications:Name: Electromagnetic Radiation Detector Battery: 3 * AAA battery (not included)Detection ranges:RF/power strength: 0-99.999pw/c mMagnetic field intensity: 0-99.999TElectric field intensity: 0-999.99v/mFrequency ranges:RF/Power strength: 50MHz-5GHzMagnetic field intensity: 20Hz-1MHzElectric field intensity: 20Hz-100MHzDetection accuracy:RF/power intensity: 0.001w/cmElectric field intensity: 0.01v/mMagnetic field intensity: 0.001TMaterial: Plasticcolour: BlackPackage Contents:1 x Electromagnetic Radiation DetectorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
