About the T-L300
In many applications, precise information about the position of buried utility lines is essential so they can be avoided during groundwork. Plans, if available, will help but may be inaccurate. The T-L300 provides a direct method of identifying the location of pipes and both live and dead cables. The use of a variable frequency transmitter allows the detection of pipes and dead cables without interference from separate mains frequency utilities. The system is suitable for route tracing, depth measurement and cable identification, where several cables are grouped together.
Key features
- Directly displays the pipe position and any deviation to the left or right of the route
- Current direction measurement to avoid interference from adjacent cables
- Real time depth and current measurements
- Light-weight with intuitive user interface
- High power transmission and high sensitivity receiver
- Depth measurement greater than 10 metres
- Optional Global Navigation Satellite System (GNSS) utilising L1 and L5 signals for accurate positioning and distance measurements
- Optional Bluetooth communication module for transmitting test data to a local PC or tablet
