PD Short Locator

Category: Characterization > Utilities Identification > Other
Reference # : Model No :

The Tinker & Rasor Model PD is used to accurately locate points of electrical contact and insulating joints on coated underground piping systems. It is unaffected by parallel lines, depths, 60 Hz or ground cover, the survey can often be, in part, conducted from a moving vehicle over the pipe. The Model PD is also a good device for pinpointing defects in coatings on buried pipelines.


This unit is also highly accurate in locating breaks in cables such as anode leads on impressed current, cathodic protection systems.
