A dual-purpose machine, simultaneously detecting electric and magnetic field radiation; audible and visual alarm, automatic alarm when exceeding the safety value; data lock, one-button radiation value lock; LCD graphic display of radiation value trends; radiation evaluation, prompt reminder if the current radiation value is safe; elegant appearance and easy one-handed operation, easy to move or measure on-site.Precise measurement: equipped with an integrated electromagnetic radiation sensor, which can display the radiation value on the clear LCD digital screen after processing by a control microchip. Magnetic field radiation is tested with optional units of mG/uT, and electric field radiation with the unit V/m. This EMF meter cannot test RF values.Audible and visual alarm: When the test result exceeds the value (0.4 µT (4 mG) or 40 V/m), the screen turns red and the indicator flashes, and the buzzer will sound an alarm. If you are testing quiet areas, you can turn off the buzzer first to avoid disturbing others.Multifunctional: Tests the average or maximum reading, and a button holds the data for viewing. Large backlit LCD screen, clear for viewing. Automatic power-off after 5 minutes of inactivity.Widely used: Primarily used for testing televisions, computers, printers, microwave ovens, refrigerators, cell towers, low-frequency household appliances, and ghost hunting, etc.Feature1. This meter can test electric field radiation and magnetic field emission to achieve optimal test results. It is used to test and monitor electromagnetic radiation levels both indoors and outdoors. It is equipped with an integrated electromagnetic radiation sensor, which displays the radiation value on the LCD digital screen after processing by a microchip controller.2. This dual-purpose instrument can test electric fields and magnetic field radiation simultaneously.3. Audible and visual alarm: When the test result exceeds the safety threshold, the instrument automatically triggers an alarm.4. Data lock: One-touch data lock for radiation values.5. LCD display of values for easier reading.6. This machine has two uses:Magnetic field and electric field testing. Automatic alarm above the safety value (40 V/m or 0.4 uT/4mG).Easy to useOperate with one hand and move or take measurements in the field. Automatically shuts off after 5 minutes of inactivity.Widely UsedPrimarily used for testing microwave ovens, televisions, 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 µT / 4 mG
