Olympus EPOCH 6LT Ultrasonic Flaw Detector – Compact Power for Advanced NDT Inspections

The Olympus Corporation EPOCH 6LT Ultrasonic Flaw Detector is a compact yet powerful non-destructive testing (NDT) device designed for professionals who demand precision without sacrificing portability. Built for rope access technicians and field inspectors, this instrument delivers advanced ultrasonic capabilities in a lightweight, ergonomic form.

Portable Design Without Compromise

The EPOCH 6LT is engineered for inspectors working in challenging environments where mobility is essential. Despite its compact size, it retains the full functionality expected from a high-performance flaw detector.

Lightweight and Comfortable

Weighing only 1.95 lb (890 g), the device features a grip-oriented design that ensures comfort during extended inspections, even when operated with one hand.

Built for Tough Conditions

Designed to meet IP65 and IP67 standards, the unit is resistant to dust, water, and harsh industrial environments. It is also drop-tested for added durability.

Clear Visibility in Any Environment

A bright, high-resolution display ensures that A-scan readings remain visible in both bright sunlight and low-light conditions.

Intuitive Operation for Efficient Workflow

Ease of use is a core advantage of the EPOCH 6LT. Its interface is designed to minimize complexity and maximize productivity.

Simple Navigation
