Flaw Detector
EPOCH 6LT
EPOCH® 6LT Portable Flaw Detector
The EPOCH® 6LT flaw detector combines ruggedness and ease of use in an instrument designed to be operated using only
one hand, enabling fast, efficient rope access inspections and maximum uptime.
Designed for Rope Access Technicians
• Free Up Your Hands: Attach the instrument to your leg
or harness and keep your hands free to scan for flaws and
maintain balance
• Comfortable: Weighs just 1.95 pounds (890 g) with a
grip-oriented weight distribution for one-handed operation
with minimal wrist fatigue
• Easy to Use: Rotary knob and simple button design make
it easy for users to navigate the menu and adjust parameters
using just their thumb, even while wearing gloves
• Clear, Bright Screen: Transflective 640 × 480 pixel display
with outdoor mode helps make A-scans clear in difficult lighting
conditions
• Tough and Reliable: Engineered to IP65/67 for dust and water
resistance and drop tested to protect against the hazards
found in rope access inspection environments

Harness the Power of Portability
No Compromises
Don’t compromise on the inspection capabilities of your flaw detector. Now, inspectors who work in rope access applications
can take advantage of the functionality they need in an instrument that attaches to their leg or harness for
hands-free operation.
Combine the EPOCH® 6LT flaw detector with the rope access accessory kit for added functionality that helps keep rope
access technicians safe during challenging inspections. The instrument fits snugly in a protective soft case that can be
securely attached to a user’s leg with the included strap or fastened to the user’s harness connection points with adjustable
safety leads. However you attach it, the kit keeps the instrument in a comfortable, secure viewing position.
With the unit secured, it’s easy to make parameter adjustments with one hand, leaving the other hand free to manipulate
the transducer or maintain balance and personal safety. The display rotates to portrait or landscape mode for optimal
A-scan viewing while the knob and buttons remain readily accessible for quick adjustments. If you’re working in a hazardous
environment, add an optional screen cover for additional protection.
The workflow of the EPOCH® 6LT flaw detector is simple and straightforward. The primary screen is a large, optimized A-scan
display that contains links to commonly used features and functions. Combined with an improved scanning workflow, users
can complete their inspections with minimal button presses and adjustments. When you do need to navigate the menu,
prominent icons make it easy to find the feature you’re looking for.
Despite its small size, the EPOCH 6LT flaw detector meets the requirements of nearly any conventional ultrasonic inspection
application and includes additional functionality for expanded connectivity.
More Functionality on the Go
• Intuitive Navigation: Two-screen, icon-based interface
• Optimized for One-Handed Operation: Hardware and
software maximize efficient one-handed operation
• Advanced Flaw Detection Capabilities: All the core
functionality of the EPOCH 650 flaw detector and meets the
requirements of EN12668-1:2010
• Fast Corrosion Defect Scanning: Optional corrosion
software combines the ease of a thickness gage with the
flexibility of a flaw detector and includes center-pin transducer
ID for faster set up
• Stay Connected: Optional wireless LAN (Wi-Fi) connectivity
for on-the-go data backups, setup downloads, efficient fleet
management, and powerful applications through the Olympus
Scientific Cloud

Rope Access Inspection Applications Powerful Corrosion and Flaw Inspection Software
Corrosion Module
With the optional corrosion module, get the best of thickness measurement and UT corrosion scanning in one instrument.
Get accurate measurements from the software’s thickness measurement algorithm, true V-path correction that accounts for
the angle of dual element transducers, and ‘do zero’ that compensates for wear on the transducer’s contact plate.
For speed and efficiency, the software enables the use of thickness gage transducers, making it easy to add a flaw detector
to your fleet of instruments. With automatic probe recognition, the software recognizes and automatically configures the
instrument for that probe. Likewise, when the AGC feature detects the probe’s signal, it optimizes the gain for optimal
thickness measurements. Once the user begins their corrosion scanning, the grid view feature makes it easy to save
thickness measurements onboard the instrument rather than having to manually record readings.
Efficient Data Management
• Compatible with GageView® Pro PC interface program
• Export files via Wi-Fi or transfer to a removable USB memory
stick
• Supports bitmap (BMP), comma-separated value (CSV), and
PDF file formats
Connected and Cloud Enabled
The EPOCH® 6LT flaw detector features cloud connectivity.
Connect your flaw detector to the Olympus Scientific Cloud
for powerful cloud-based tools, including:
• Wireless firmware upgrade
• File backup and archiving
• Remote file access and management
Cloud file management includes all EPOCH 6LT file types, as
well as exported report formats and image files. This remote
data sharing capability makes it easier than ever to report
and communicate your inspection results.
