ET925 Style Description: This radiation survey meter can test electric fielo radiation and magnetic field emiion to reach the optimal test result. It is used to test and learn electromagnetic radiation situation indoor and outdoor. It is equipped with a built-in electromagnetic radiation sensors which can display the radiation value on LCD digital display after proceing by the control micro-chip. You can make reasonable proceing or taking effective prevents measures toward the electromagnetic radiation according to the test result. If you need it, come and have a try, it will not let you down. Features: Adopt large LCD display screen, the value can be clearly displayed on the screen and easier for you to read, and give you a better experience. This detector can simultaneous detection of electric and magnetics field radiation for you, allows you to get two important values in one test. Sound and light dual alarm function, it will automatic alarm when the test value over the safety value. Data hold function: You can short pre "Power / HOLD" button and the reading will be locked and [HOLD] icon shows up on the screen, pre again to resume normal measurement and [HOLD] icon will not show. Portable size and easy to carry, you can use it easily with one hand and carry it with you to anywhere you want to use. Radiation aement function, which can indicating if current radiation value is at safety level, three color light indicating the current magnetic field states: safety, alert, avert, and if the electric field data over the safety state, the screen will become red to alarm you. Wide applications: This tester can be used for electromagnetic radiation monitoring of House and apartment, office, outdoor and industrial site, electromagnetic radiation test of mobilephone, computers, TV set, refrigerator and high voltage cable radiation test, radiation protections product test such as test effects of radiation proof clothes, radiation proof film and other prevents.
