This EMF Meter can test electric field radiation and magnetic field emission to reach the optimal test result. It's widely used to test and learn electromagnetic radiation situation indoor and outdoor. Equipped with a built-in electromagnetic radiation sensor, which can display the radiation value on the clear LCD digital display after processing by control micro-chip.Features:One EMF Meter with Two Uses - Testing the electric field and the magnetic field radiation at the same time.Measure Radiation - of TV, induction cooker, rice cooker, refrigerator, computer, appliances, electrical wires, etc.Sound-light Alarm - When the test result exceeds the safe value, the instrument will alarm automatically.Data Hold & Max Measurement - One-key lock the radiation value.Large & Clear LCD Display - of the values for easy reading.Easy to Operate with Easy One-hand Operation - Easy to carry and make field measurement.Measure the Environment Temperature  - with 2 temperature units (℃ and ℉).Specifications:Brand Name: Meterk     Color: Black   Material: ABS Display: 4 digits LCD DisplayUnit: mG (Electric Field); μT (Magnetic Field): Electric: 0～2000mG; Magnetic: 0～200μTAccuracy: ±5% (50μT to 200μT)μT at 50Hz or 60HzResolution: 1mG, 0.1μTAlarm Threshold: 40mG, 0.4μTTemperature: 0～50℃ / 32～122℉Test Bandwidth: 30Hz-300HzNumber of : Single Inductive HeadSampling Rate: 0.5 SecondsTest Mode: Bimodule Synchronous TestOver Indication: LCD Displays "HI"Operating Temperature: 0～50℃, Relative Humidity 0～80%Storage Temperature: -10～50℃, Relative Humidity: 0～70%Power Supply: 3 * 1.5V AAA Battery (Included)Item Size: Approx. 130 * 50 * 27mm / 5.12 * 1.97 * 1.06in (L * W * H)Item Weight: Approx. 107g / 3.78ozPackage Size: Approx. 16.5 * 7.7 * 3cm / 6.50 * 3.03 * 1.18in (L * W * H)Package Weight: Approx. 147g / 5.18ozPackage List:1 * Electromagnetic Radiation Detector(EMF Meter)1 * User Manual (English + French + German + Italy + Spanish)
