PopisThe HHCL10 is ideal for pinpointing the location of electrical cables and metal, water, or gas pipes behind walls, above ceilings or under floors. It can also trace circuits, detect open- and short-circuits, find outlets covered by plaster, identify a circuit’s breaker, and locate blockages in plastic pipes. Makes it safe to break through any wall by revealing and locating hidden infrastructure up to 2 m (6.6') behind it, and eliminates the need to find and read construction drawings before starting a job. Transmitter and receiver communicate on any of eight channels and display readings on a big, bright, multi-function graphic LCD. Both units also include a flashlight (for illuminating dark areas) and a buzzer that can be muted. Transmitter has three power levels; receiver has variable sensitivity. Compatible with one- or two-pole circuits. Used with a metal rod, system can locate blockages and constrictions in plastic pipes.
