AT-3500
Underground Cable /
Pipe Locator System
Keep productivity high and operational costs low with the Amprobe
AT-3500. It’s the rugged, economical solution for locating underground
energized and de-energized wires, cables and pipes. Great for parking lot
and airport lighting applications, it precisely pinpoints buried services with
exceptionally fast sound and meter response. Take depth measurements
with the press of a button. The backlight multiple-segment bar-graph
digital display plus audible indicators show and tell readings. The AT-3500
employs the proven 33 kHz frequency for most locating applications. To
avoid lines at utility construction sites, it also offers the highly sensitive
power and radio modes.
Features
• Locates underground energized and
de-energized wires, cables and pipes
• Three testing modes for best
accuracy
– Passive Power (50 / 60 Hz)
– Passive Radio (RF)
– Active T-3500 signal generator
with induction mode or directly
connected to the cable with test
leads or optional clamp
• Active Mode Depth measurement up
to 16 ft (4.9 m)
• Semi-automatic gain control – fast
signal location and control
• 33 kHz active frequency – best
frequency for general locating
• Precise pinpointing of buried
services and exceptionally fast sound
and meter response with backlight
multiple-segment bar-graph digital
display and audible indicators
• Complete instrument, ready for use
with receiver, transmitter, connection
cable, ground stake and ground cable
