This electromagnetic radiation detector is compact, lightweight and portable, with a large, clear-definition color screen and large, colorful font design, three parameters are detected simultaneously, fast detection of radio frequency 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 exceed 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.  Features:  Compact, lightweight and portable, with a built-in high-accuracy chip, it is practical and reliable to use.  With a large, clear-definition color screen and large, colorful font design, it can easily cope with dim and bright environments to give you a more comfortable experience.  Three parameters are detected simultaneously, fast detection of radio frequency 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 exceed 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  Material: ABS Color: black, white (optional) Battery: 3 x AAA battery (not included) Detection ranges: Radio frequency or power strength: 0-99.999pw or c m Magnetic field intensity: 0-99.999μT Electric field intensity: 0-999.99v or m Frequency ranges: Radio frequency or Power strength: 50MHz-5GHz Magnetic field intensity: 20Hz-1MHz Electric field intensity: 20Hz-100MHz Detection accuracy: Radio frequency or power intensity: 0.001μw or cm Electric field intensity: 0.01v or m Magnetic field intensity: 0.001μT Display: 66 x 49mm or 2.60 x 1.93in Item size: 127 x 65 x 23mm or 5.00 x 2.56 x 0.91in Item weight: 130g or 4.59ounce Package size: 140 x 90 x 35mm or 5.51 x 3.54 x 1.38in Package weight: 220g or 7.76ounce Packing List: 1 x Electromagnetic Radiation Detector Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
