Feature:1. This ultrathin smart digital multimeter is light and slim, with a frosted exterior that is easy to carry.2. The ultrathin digital multimeter can be used for AC voltage/frequency measurement, and it can be measured immediately without shifting gears.3. LIVE neutral live wire discrimination function, when a single meter pen touches the live wire meter, there will be a rapid alarm sound, the voltage strength simulation bar is full on the screen, and the neutral/ground wire simulation bar does not respond.4. Easily distinguish whether there is electricity or not, built-in high-sensitivity AC voltage probe, the screen simulates the electric field strength.5. The true RMS voltage test uses a true RMS chip to measure accurately and reliably.Specification:Item Type: Digital Multimeter.Material: ABSUniversal Meter Size: Approx.
