Widely used to test and learn electromagnetic radiation situation indoor and outdoor, this EMF Meter can test the magnetic field radiation, electric field radiation and the temperature of the testing environment. With a built-in electromagnetic radiation sensor, this tester can display the radiation values on the clear LCD digital display screen after processing by the control micro-chip.                    Features:              -Proper Size: Easy to carry and operate with one hand.              -LCD Display: Large & clear, easy to read values.              -Flashlight Function: See the values clearly in the dark.              -One EMF Meter with Three Measurements: Measurements of the magnetic field radiation, electric field radiation and the temperature.              -Multiple Units Conversion: mG/µT/(V/M)/℃/℉              -Data Hold & Max Measurement: One-key locks the data.              -Sound-light Alarm: When the test result exceeds the safe value, the instrument will alarm automatically.              -Wide Applications: Measuring radiation of TV, induction cooker, rice cooker, refrigerator, computer, appliances, electrical wires, etc.                    Specifications:              Material: ABS              Color: Black              Power Supply: 1 * 6F22 9V Battery      (Not Included)              Automatic Shutdown: No operation for 15 minutes              Operating Environment: 0-40℃/32-104℉, 45%-80%RH              Frequency Range: 5Hz-3500MHz              Measurement Range of     Magnetic Field Intensity: 0.1-199.9mG / 0.01-19.99µT              Resolution Ratio: 0.1mG / 0.01µT              Alarm Threshold: > 4.0mG / > 0.4µT              Measurement Range of     Electric Field Intensity: 1-1999V/M              Resolution Ratio: 1V/M              Alarm Threshold: > 40V/M              Measurement Range of     Ambient Temperature: 0〜50℃/ 32〜122℉              Resolution Ratio: 1℃/℉              Accuracy: ±1.5℃/ 3℉                                                                                                                              Item Size: Approx. 19.2*5.38*3.5cm / 7.56*2.12*1.38in              Item Weight: Approx. 110g / 3.88oz              Package Size: Approx. 23*8*5cm / 9.06*3.15*1.97in              Package Weight: Approx. 200g / 7.05o                    Packing List:              1 * Electromagnetic Radiation Detector (EMF Meter)              1 * Users Manual (English)              1 * Cloth Bag
