Handheld electromagnetic radiation detector

Electromagnetic waves (also known as electromagnetic radiation) are the same-phase oscillating and mutually perpendicular electric and magnetic fields that move in the form of waves in space, and their propagation direction is perpendicular to the plane formed by the electric and magnetic fields, effectively transferring energy and momentum. Electromagnetic radiation can be classified according to frequency, from low frequency to high frequency, including radio waves, microwaves, infrared, visible light, ultraviolet light, X-rays and electromagnetic waves (also known as electromagnetic radiation). It is composed of electric and magnetic fields that oscillate in phase and are perpendicular to each other. It moves in the form of waves in space, and its propagation direction is perpendicular to the plane formed by the electric and magnetic fields, effectively transferring energy and momentum. Electromagnetic radiation can be classified according to frequency, from low frequency to high frequency, including radio waves, microwaves, infrared, visible light, ultraviolet light, X-rays, gamma rays, and so on. The electromagnetic radiation that the human eye can receive has a wavelength between 380 and 780 nanometers and is called visible light. As long as it is an object whose temperature is greater than absolute zero, it can emit electromagnetic radiation, and there is no object with a temperature equal to or lower than absolute zero in the world.

Tip: At present, Sweden has become the first country in the world that officially believes that low-frequency electromagnetic fields with an intensity above 0.2μΤ (2mG) are harmful to humans. When the display frequency of this machine exceeds 105HZ, it will If it is harmful to the human body, take away or protective measures. Note: 1 This instrument has a small number of grounded computers that cannot be detected. Please use another corresponding instrument of our factory to detect grounding equipment. 2 When the tester appears on the left side of the display; ‘-’ indicates that the battery will be used up, please replace it urgently. Note: 1. μΤ: Micro Tesla mG: milligauss 2. Before 1μΤu003d10mG, Sweden has become the first country in the world that officially believes that low-frequency electromagnetic fields above 0.2μΤ (2mG) are harmful to humans. This machine When the display frequency exceeds 105HZ, it will be harmful to the human body, so keep away or protective measures should be taken. Note: 1 This instrument has a small number of grounded computers that cannot be detected. Please use another corresponding instrument of our factory to detect grounding equipment. 2 When the tester appears on the left side of the display; ‘-’ indicates that the battery will be used up, please replace it urgently.
