MASTECH MS6818 Wire Cable Tracker

The MASTECH MS6818 is a portable wire cable tracker and metal pipe locator designed for detecting buried cables and pipelines. It integrates an AC/DC voltmeter function measuring 12 to 400V voltage linearly. The transmitter features an LCD screen displaying transmitting power, battery status, and voltage warnings. Both transmitter and receiver offer mute mode operation for quiet environments.

Electricians and maintenance technicians tracing

This tool suits professionals locating cables, electrical lines, water or gas pipes buried in walls or earth. It identifies interruptions, short circuits, and blown fuses in concealed wiring. It also traces sockets covered by plaster and detects faults in floor heating systems. Buyers needing wireless signal detection or non-contact voltage testing without a transmitter should look at other instruments.

Integrated AC/DC voltmeter 12 to 400V

The defining specification is the transmitter's built-in AC/DC voltmeter measuring 12 to 400V voltage on a linear basis. This allows direct mains voltage verification while tracing lines. The LCD shows real-time voltage, AC/DC status, and a warning symbol for hazardous voltage. Receiver sensitivity adjusts manually or automatically with auto frequency sweep for precise signal detection.

Questions about this item

Should I choose the MS6818 or a different model for tracing buried cables?

The MS6818 locates cables, water or gas pipes in walls or earth, finds breaks and short circuits, identifies fuses and traces sockets covered by plaster.

What does the 12 to 400V AC/DC range mean when I am testing a live circuit?

The built-in voltmeter measures mains voltage linearly from 12 V up to 400 V AC or DC, and the LCD shows the value plus an AC/DC status indicator and a warning symbol.

How does the transmitter/receiver interface work and what limits the tracing distance?

The transmitter injects a coded signal that the receiver picks up; sensitivity is adjustable manually or automatically and the receiver can sweep frequency to maintain detection.
