Features

Model 715 by Nilsson Electrical Laboratory Inc. is an all solid state, conductive-type pipe and cable locator. It is great for solving cathodic protection problems as well as determining exact location and depth of pipes and cables. A signal is applied to pipe or cable and can be accurately followed over long distances. The transmitter tone is designed with variable frequency and interrupter rate, and can be adjusted for distinctive signal under any conditions. It has three output impedance taps for efficient matching to all soil conditions. The Transmitter and Receiver are interlocked, preventing storage with batteries turned on.

Power can be provided by a 12 Volt lantern battery or by a external 12 Volt source. A battery warning light indicates when the battery needs to be replaced. Model 715 can also be powered by an external rechargeable 12 Volt Battery, Nilsson Model 110 (described below).

The transmitter and receiver assembly are housed in a rugged, lightweight, weatherproof aluminum case measuring 7" x 7" x 11". This case provide ample storage room for accessories. Approximate weight is 9 lbs.

Nilsson Model 110
Rechargeable 12 Volt Battery Pack

Much more economical than replacing lantern batteries
Recharges Overnight - Cannot be Overcharged
The battery can be recharged overnight by plugging into any 110 Volt AC outlet. It can also be recharged from a running 12 Volt vehicle system by using an automobile recharging cable. The self-contained, solid-state recharging circuit is so designed that the battery can be recharged hundreds of times and cannot be overcharged. A 110 Volt AC charging adapter is included.
Specially Designed for Model 715 Pipe and Cable Locator and Models 825 and 830 Current Interrupters
Nilsson Electrical Laboratory, Inc. has developed the Model 110, 12 volt rechargeable battery pack for use with the Nilsson Model 825 and 830 Current Interrupters. The Model 110 can also be used with any equipment requiring a 12 Vold DC power source.
Fits in same Battery Clamp
The battery will clamp directly in either the Model 715 Pipe and Cable Locator or the Models 825 and 830 Current Interrupters in the same space as the 12 Volt lantern battery normally supplied.
Gelled Electrolyte Provides Higher Current Capacity
Using the latest developments in rechargeable batteries, the Model 110 employs a gelled electrolyte in a sealed battery, providing much higher current capacity than other rechargeable batteries. The Model 110 can be used over a wide operating temperature range under rugged field conditions.
