The Tinker & Rasor Model AP Holiday Detector is a portable electrical inspection instrument for use on both large and small diameter pipe as well as flat surfaces when such surfaces are coated with a high electrical resistant material and the surface beneath the coating is electrically conductive, such as metal or concrete. It operates equally well on damp or dry surfaces, so is desirable where humid conditions prevail.

Twenty (20) voltage settings are settable in two ranges from 1 kV to 14 kV.

Power to the instrument is furnished by a sealed, rechargeable, nickel cadmium battery which requires NO maintenance other than recharging. A single charge is suitable for a full day's work.

Weighing only eight pounds, the detector can be comfortably belt-mounted or carried by the handle. When faults or foreign particles in the protective coating are encountered by the inspection electrode, a distinctive audible signal heard.

Typical applications are check coatings on pipelines (internal & external), tanks, concrete, sewers, and manholes.
