Features: Compact, 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 easily cope with and 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 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 m Magnetic field intensity: 0-99.999T Electric field intensity: 0-999.99v/m Frequency ranges: RF/Power strength: 50MHz-5GHz Magnetic field intensity: 20Hz-1MHz Electric field intensity: 20Hz-100MHz Detection accuracy: RF/power intensity: 0.001w/cm Electric field intensity: 0.01v/m Magnetic field intensity: 0.001T Material: Plastic colour: Black Package Contents: 1 x Electromagnetic Radiation Detector Only the above package content, other are not included.
