Practical Electromagnetic Radiation Detector Handheld EMF Tester EMF Meter Portable 5 LED Gauss Meter Magnetic-Field Test Meter for Home Vacuum Cleaner Hair Dryer The EMF Meter is a user-friendly device designed to measure magnetic field strength. It can be used both indoors and outdoors to measure electronic devices or power lines. There are 5 indicator lights, each with a different color. These colors represent different field strengths that can help you easily read test results and quickly determine the safety status of the magnetic field. Suitable for detecting high, medium, and low-frequency electromagnetic radiation, magnetic field strength, and sensitivity. It can be used for computers, TVs, hair dryers, vacuum cleaners, antenna signals, routers, electric fans, microwaves, and other electrical appliances. Features: 【EMF Radiation Tester】: This electromagnetic radiation detector is mainly used to safely identify potentially harmful high EMF radiation, and help you know about the surrounding environment. The measured frequency ranges from 50Hz to 20000Hz, ensuring the effective detection of electromagnetic fields generated by various common electrical equipment and power lines. 【5-LED Indicator Lights】: The 5-LED indicator represents different radiation values, helps you read test results in the dark and sunlight, and quickly determines the safety status of the magnetic field. The green indicator light indicates the normal and low magnetic level area, the yellow indicator light indicates the mid magnetic level area, the orange indicator light indicates the high magnetic level area, and the red indicator light indicates the extremely high magnetic level area. 【Compact & Battery Operated】: This EMF meter is powered by 1pcs 9V battery (not included, needs to be prepared by the user), highly efficient operation, and saves power. The small size is convenient e and easy to hold. The combination of small, lightweight size and battery operation makes it easy to carry around for electromagnetic radiation detection anytime, anywhere, enhancing ease of use. 【Scope of Applications】: This product can detect high, medium, and low frequency electromagnetic radiation, magnetic field strength, and sensitivity. It can be used for computers, TVs, hair dryers, vacuum cleaners, antenna signals, routers, electric fans, microwaves, and other electrical appliances. 【Integrated Electromagnetic Detection Assistant】: As a compact and easy-to-use magnetic field strength meter, the device, with its accurate radiation detection, intuitive LED indication, convenient battery operation, and wide applications, is a perfect tool for users to assess the electromagnetic safety conditions of their living and working environments, and to help create a healthy and hazard-free living and working space.
