EPOCH XT
Advanced Ultrasonic Flaw Detector
Key Features
■ EN12668-1 compliant
■ Tested for explosive atmosphere, vibration
and shock
■ Designed to meet IP67 requirements to
withstand harsh environments
■ Direct access hand-held design
■ Split screen view of A-scan and param-
eters for fast calibration verification
■ Dynamic DAC/TVG Standard

The EPOCH XT Ultrasonic Flaw Detector is designed for great inspection
flexibility and for use in extreme environments. It combines a multitude
of enhanced flaw detection and measurement features, a bright multicolor
LCD, versatile battery options, powerful data management, and numerous
software features in a compact unit with a sealed case designed to meet IP67
requirements.
The EPOCH XT allows the operator access to a wide variety of standard pulser
and receiver features that make the unit flexible to a large number of flaw
detector applications. With up to 475V pulse energy combined with Olympus
NDT’s PerfectSquare
™
tunable square wave pulser, the EPOCH XT is capable of
high penetration applications beyond the standard flaw detector. And with an
arsenal of optional software features, the instrument can be enhanced to meet
the needs of nearly any conventional ultrasonic inspector.
■ Multiple battery options – can be used
with lithium-ion, NiMH, or C-cells
■ Host USB port for direct printing and storage
to USB drives
■ Client USB Port for PC communication
■ Perfect Square
electronically controlled on both the
leading and trailing edges to maximize
transducer performance and near-surface
resolution.
