C.Scope MXL4-D Data logging Multi Frequency Locator (MXL4-D)

Product Description:

The C.Scope MXL4-D Datalogging Multi Frequency Locator is a useful cable locator and tracer which stands out because of its large detection range for signal frequencies. Multiple detectable frequencies allow the locator to find and trace all sorts of underground pipes and cables, right the way from thin streetlight wiring to large utility pipes. The highly sensitive locator is also optimised for negating interference.

In addition to an all purpose 33kHz signal, the C.Scope MXL4-D can also pick up a 131kHz signal which is suitable for locating or tracing short, thin or unearthed wires. The two frequencies can be simultaneously detected for utility avoidance. For tracing longer cables, the locator can pick up an 8kHz signal, whilst two ultra low frequency signals – 512Hz and 640Hz – are available for specialist applications such as locating blockages in metal pipes. This is all performed in conjunction with the C.Scope MXT4-D Transmitter.

Other operating modes on the C.Scope MXL4-D offer excellent flexibility. As a standalone instrument, the locator works in power and radio mode which can detect signals from live electric current and radio-type signals from subterranean metal surfaces. AllScan mode is also available which detects signal frequencies which may lie outside the capabilities of other modes.

Further to its multiple frequencies and operating modes, the C.Scope MXL4-D provides accurate depth indications from 0.1 to 9.99m with a resolution of just 0.1m. The locator’s peak hold function helps pinpoint pipe/cable location and trace the line of the utility by remembering where the signal is strongest. AlarmZone™ gives the user warning if obstacles are particularly close to the surface. The Swing Indicator sounds when the locator is swinging too much to take accurate readings.

The datalogging functionality of the C.Scope MXL4-D means that it can store roughly 12-months’ worth of data on its 2GB internal memory. This information can be transferred by a USB cable to a PC for further analysis and storage with free C.Scope PC Toolkit software. Readings are displayed on the locator’s clear LCD screen.

An automatic daily self test helps ensure accuracy and the C.Scope MXL4-D had weatherproof, IP65-rated casing for use in challenging environments. A three-year warranty is provided by the manufacturer. To make the most of your purchase, you may wish to consider adding the C.Scope MXT4 Transmitter by clicking the checkbox above.
