Made of fine quality material, practical, easy to operate and use, wide application range, has a long service life. Features: Compact and lightweight: easy to use and carry. Dual mode: this voltage detector features manual / auto mode, it is convenient to detect and indicate the existence of AC voltage in auto mode, or applied to more occasions in manual mode. Freely adjustable sensitivity: the sensitivity of this detector can be adjusted to any value according to your needs. When adjusting to low sensitivity, it can more accurately distinguish the specific situation in complex lines. 8 LED indicators in 3 colors: this detector can intelligently judge the strength of detected voltage by automatically lighting different color and quantity LED indicators. Live / Neutral wire distinguish: safe to distinguish live / neutral wire by comparing the detected voltage strength. Insulation protection probe: the detector probe adopts ABS insulation design, which can protects you from electric shock while improving the sensitivity. Breakpoint locate: safe and fast to locate the breakpoint of the live wire by measuring the change in voltage strength. Flashlight function: flashlight design lets you test efficiently and comfortably.
