😊[Safety Comes First]Adopting NCV induction probe, the voltage tester enables you to detect voltage without any contact which largely avoids electrical shock and ensures your safety, you only need to put the tip of the detector near an outlet or power cord. 😊[Know Your Testing Result Clearly]Besides Large LCD display, audible and visual alarms are also available. The higher voltage the tester detects, or the closer the tester approaches the voltage source, the louder and more frequent alarm sounds. The green light blinks indicating low voltage while the red light indicates high voltage. 😊[Achieve More Flexible Testing]The non-contact voltage tester adopts dual and switchable sensitivity (AC 12V-1000V / 48V-1000V), LOW is ideal for detecting doorbells, thermostats and power strips. The voltage strength be shown as 1~6 level, allowing you to detect the live or neutral wire easily. 😊[Temperature Measurement & Flashlight] Compared to most common voltage testers, our electric tester is designed with a function of measuring ambient temperature, enabling users to hazardous situations. Meanwhile, the flashlights help you have a better understanding of the environment in darkness. 😊[Portable and -saving Design]The voltage tester pen with pocket-size and clip is convenient for carrying. Plus, automatic power off after 5 minutes without operation or signal detection to conserve and extend battery life. Note please: It needs 2PCs of AAA batteries (Not included in the package)., Weight: 0.15211896078 pounds, Manufacturer: Wesafrae
