Voltage Detector
ZhangZhou Weihua Electronic co.,ltd (WHDZ)
A device that tells the user whether an object has an electrical charge. It can be a simple, pen-shaped piece of testing hardware that indicates the presence of electricity, or it can be an advanced tool used to detect precise voltage levels in electrical systems. Voltage detectors use either visual or audio cues to tell the user whether voltage is present. Some are equipped with lights and numbers that indicate the level of voltage, while a less advanced voltage detector might simply make a beep to indicate that a level of detectable voltage is present.
