Detecting cables,electrical lines,water/gas supply pipelines buried in wall or earth

Detecting interruptions and short circuit in cables and electrical lines buried in wall or earth

Detecting fuses and assigning current circuits

Detecting interruptions and short-circults in floor heating

Detecting sockets and distribution sockets having accidentally been covered by plastering

Features :

The transmitter is integrated with the function of AC/DC voltmeter,which can measure 30 to 400V AC/DC voltage on a linear basis.

The screen of the transmitter can display preset transmitting power,transmitted codes,its own battery energy,mains voltage detected,AC/DC status of mains voltage detected,and warning symbol for mains voltage.

The Transmitter has the function of self-inspection to detect its own working status and to display it on the LCD screen for user's reference

The sensitivity of the receiver can be adjusted either manually or automatically

The receiver can sweep frequency automatically,both the transmitter and the receiver can work under mute mode

Additional transmitters are available for expansion or to differentiate between multiple signals compactness,durability and portability
