Features: 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 : the universal meter can measure AC or DC voltage, resistance, capacitance, frequency, diode, continuity, firewire recognized, etc. Household Electromagnetic Radiation Detection: induction area to identify high frequency electromagnetic radiation emitted by microwave oven, electric fan, or air conditioner. And has icon and 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 30, 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 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 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.
