LCD Digital Voltage Tester Intelligent RCD Power Socket Detector Phase Polarization

DIGITAL DISPLAY: With high-definition display, you can clearly see the value on the screen in a dark environment, which is easy to read and very practical. SAFETY: a key to instantly discover the safety of the circuit, whether there is a risk of leakage, avoiding electric shock and ensuring your safety. LEAKAGE PROTECTION: If the leakage switch test switch is pressed and there is no tripping or power failure, there is no leakage protection, but leakage protection. MULTIFUNCTIONAL: Not only suitable for simple non-contact voltage detection, but also for complex circuit detection. FIELD OF APPLICATION: It can meet most electrical testing requirements and is ideal for safety inspections of electrical circuits at home, as well as in schools, factories and offices, etc.
