1 Based on volumetric testing at a known fixed depth. True depth accuracy depends on factors such as ground composition, utility characteristics and the locate frequency / signal strength employed. Always follow local safe digging guidelines.
2 The RD7200 will locate to greater depths in the right conditions, but depth accuracy will be compromised. Depth measurement will not be displayed beyond these depths.
3 Water projected by a nozzle at a pressure of 30kPa /0.3 bar / 4.4 psi in accordance with BS EN 60529 1992 A2 2013.
4 At very low temperatures, battery life will be degraded and measurement precision may be reduced.
Advanced features such as Compass, TruDepth™ and a broad range of locating frequencies make the RD7200 the perfect choice for all industries.
ConstructionAccurate and simple to use, the RD7200 comes with eight active and three passive frequencies that cover the majority of site locating tasks. A rugged, IP65 rated casing along with a high contrast screen make it suitable for use in all weather conditions.
PowerIn complex power environments, with multiple signals from high voltage equipment and cables, Radiodetection’s Dynamic Overload Protection reduces the effect of interference and Power Filters can be used to trace a single target line amongst multiple cables.
Water and PipelineA wide choice of active frequencies allow conductive pipes to be traced for long distances.Where sondes or cameras are used to survey pipes made from a variety of materials, including cast iron, clay, fibre, concrete and brick, the four RD7200 sonde frequencies are ideal for quickly locating and tracing their position. Pipes with Cathodic Protection System can be followed using the CPS passive mode. CPS compass mode ensures alignment with the target pipeline. TelecomThe RD7200 features higher frequencies to locate high impedance lines and sonde frequencies for duct and conduit tracing. Higher frequencies can also be used to trace sheathed domestic cables without grounding connections.Cable sheath faults can be located to within 10 cm using 8 kHz Fault Find mode with a Radiodetection A-Frame |
