2-in-1 EMF Multimeter: the digital tester has function of Electromagnetic Field Radiation Detector and Universal Meter, which is very suitable for professionals and household using Multifunctional Multimeter with Wide Test Range: the universal meter can measure AC/DC voltage, resistance, capacitance, frequency, diode, continuity, firewire recognized, etc. Household Electromagnetic Radiation Detection: top induction area to identify high frequency electromagnetic radiation emitted by microwave oven, electric fan, or air conditioner. And has icon & 3-color analog bargraph displayed once the electromagnetic radiation recognized, buzzer sounds simultaneously Smart Functions: automatic identification of AC voltage, DC voltage, resistance at auto mode; measuring diodes within 1.0V; when the resistance is less than 30Ω, the buzzer will sound up at the continuity function; and the buzzer sounds when live voltage signal recognized. Rechargeable Li-ion Battery: built-in 800mAh rechargeable li-ion battery, convenient to use and recharged. Auto power off when there is no signal input within 5 minutes High Precision Display: auto ranging with 9999 counts smart multimeter with data hold function, and the 3.5-inch large EBTN colored LCD greatly enhance the reading experience, the value is very easy to read even under the sunlight or poor light condition Safety Assurance: with full measuring range overload protection, double insulation protection, CAT.II 600V and CAT.III 300V safety level. Pocket Size Digital Handheld EMF Multimeter: compact portable size designed with a detachable durable sleeve, and a storage pouch for protecting it against shocks, friction and bumps Specifications: DC voltage: Range: 0~620V (DC mode) 0.5~620V (Auto mode), Resolution: 0.001V (Accuracy ±(0.8%+3)) AC voltage: Range: 0~620V (AC mode) 0.5~620V (Auto mode), Resolution: 0.001V (Accuracy ± (1.2% + 5)) Resistance: 1Ω~10.00MΩ, resolution: 0.1Ω (Accuracy ± (1.2% + 3)) Capacitance: 0.5nF~1000μF, resolution: 0.1μF (Accuracy ± (3.5% + 8))/ 1000μF~6000μF, resolution: 0.1μF (Accuracy ± (4.5% + 10)) Frequency: 10Hz~1000Hz, resolution: 1Hz (Accuracy ± (2.0% + 10)) Diode: less than 1.0V diode automatic identification Automatic shutdown: 5 minutes Battery: 800mAh
