1. Features: - Practice: The electromagnetic radiation tester has successfully tested and optimized the compatibility of electric and magnetic field radiation to verify and understand the current indoor and outdoor electromagnetic radiation conditions. - Radiation protection products: The EMF tester is equipped with an electromagnetic radiation sensor, which is processed by a micro - controller chip and then displays the radiation value on the LCD digital display. Based on the test results, electromagnetic radiation can be reasonably controlled or effectively avoided. - Alarm function: The digital multi - field EMF meter can simultaneously detect electric and magnetic field radiation in one device. It has an audible and visual alarm function and will automatically alarm when the safety value is exceeded. It also has a data locking function, allowing you to lock the radiation value with one key. - LCD display: The digital electromagnetic field radiation detector has an LCD display that shows the trend of radiation values in a graphical form, enabling you to evaluate the radiation and kindly reminding you of the safety of the current radiation level. - Wide application: The electromagnetic radiation detector is small in size, portable, and can be operated with one hand, facilitating mobile or outdoor measurements. It is suitable for homes, offices, outdoors, laboratories, industrial sites, etc. 2.

Package list: - 1 x Electromagnetic radiation tester - 1 x Manual 4. Notes: - Zero setting of electric/magnetic field: After power - on, press and hold the AVG/VPP and UNIT buttons simultaneously. After about 2 seconds, enter the zero - setting interface. When the magnetic field value flashes and is less than 0.1 uT, short - press the power/data hold key to reset the magnetic field value. After zero - setting is completed, long - press the AVG/VPP key to exit the zero - setting interface, or long - press the power/data hold key to turn off the device. - When the battery icon is empty, please replace the battery in time. - For high - voltage equipment, long - distance measurement is sufficient. Remember to pay attention to safety. - Due to possible electromagnetic field interference in the environment, the product may show a very small reading when powered on. This is not a device defect. - For manual measurement, please allow for some errors.
