Product Description

EPOCH LTC: Rugged Handheld Flaw Detector

The EPOCH LTC is a mid-level, handheld ultrasonic flaw detector in a compact 2.12 lbs (0.96 kg) vertical case. It is a full-featured instrument with EN12668-1 compliance and a wide variety of standard features as well as specialized options to meet your inspection needs.

The EPOCH LTC Digital Ultrasonic Flaw Detector offers state-of-the-art technology in a package that is compact and lightweight 2.12 lbs (0.96 kg). Based on the design of the class-leading EPOCH XT, the EPOCH LTC is a full-featured instrument with EN12668-1 compliance and a wide variety of standard features as well as specialized options to meet your inspection needs.

Ultrasonic flaw detection is widely used for locating and sizing hidden cracks, voids, disbonds, and similar discontinuities in welds, forgings, billets, axles, shafts, tanks and pressure vessels, turbines, and structural components.

The instrument features a bright multi-color transflective display with full VGA (640 x 480) resolution providing a high resolution A-scan and superior visibility in all lighting conditions, including direct sunlight. The EPOCH LTC is also designed to the requirements of IP67, assuring that the instrument will perform in the harsh environments common in the inspection field.
