The ZOYI ZT-DB03 is a non-contact AC voltage detector designed for electricians, installation engineers, maintenance teams, property inspectors and experienced DIY users.
It allows users to check for the possible presence of AC voltage near insulated cables, sockets, switches and electrical equipment without making direct contact with an exposed conductor.
The adjustable sensitivity function helps users adapt the detector to different environments. Higher sensitivity can assist with detecting electric fields through insulation or at a greater distance, while a lower setting can help narrow down the position of a nearby conductor.
Its slim pen-style housing supports comfortable one-handed operation and fits conveniently inside a pocket, tool belt or service bag. The illuminated display and LED torch make it practical for lofts, equipment cabinets, consumer units and areas behind appliances.
