One machine for dual use, simultaneous detection of electric and magnetic field radiation; Sound and light alarm, automatic alarm beyond the safe value; Data lock, one-button lock radiation value; LCD graphic display trend of radiation value; Radiation evaluation, intimate reminder whether the current radiation value is safe; Elegant appearance and easy to operate with one hand, easy to move or measure on site.Accurate measurement: Equipped with a built-in electromagnetic radiation sensor, which can display the radiation value on the clear LCD digital screen after processing by micro-control chip. Testing magnetic field radiation with optional units mG/uT, electric field with unit V/m. This emf meter can not test RF value. Sound and light alarm: when the test result exceeds the value (0.4 ut (4mG) or 40 V/m), the screen will turn red and the indicator will flash, and the buzzer will alarm. If you test some quiet areas, you can close the buzzer first, avoid disturbing others. Multi-function: test the average or maximum value reading (Maximum), and one key holds the data for a view. Large backlit LCD display, clear for viewing. Auto power off after 5 minutes without operation. Widely used: mainly used for testing TV, computer, printer, microwave oven, refrigerator, cell towers, for low-frequency household appliances, and ghost hunting, etc. Feature 1. This meter can test electric field radiation and magnetic field emission to achieve the optimal test result. It is used to test and learn the electromagnetic radiation situation indoors and outdoors. It is equipped with a built-in electromagnetic radiation sensor, which can display the radiation value on the LCD digital screen after processing by micro-control chip. 2. One instrument has two uses, it can test the electric field and magnetic field radiation at the same time. 3. Sound and light alarm, when the test result exceeds the safe value, the instrument will automatically alarm. 4. Data lock, one-key lock of the radiation value. 5. LCD display of values for easier reading. 6. One machine with two uses. Testing magnetic field and electric field. Automatic alarm above the safety value (40 V/m or 0.4 uT/4mG).Easy to useOne-handed operation and move or make measurements in the field. Automatically turns off after 5 minutes without operation.Widely usedMainly used for testing microwave ovens, TVs, hair dryers, computers, low-frequency household appliances, wires, etc.SpecificationsElectric field:Range: 1 V/m-1999 V/mAlarm threshold: >40 V/mResolution: 1 V/mMagnetic field:Range: 0.01 mhz-99.99 mhz/0.1 mG - 999.99 mGAlarm threshold: > 0.4 ut/4mG
