GE Epoch 4 is a high-performance portable ultrasonic flaw detector developed for industrial NDT applications. Featuring lightweight design and rugged housing, the instrument is suitable for field on-site inspection under various harsh working environments.

It supports standard ultrasonic inspection functions including flaw location, sizing and amplitude evaluation. Equipped with high-resolution display, intuitive operation menu and flexible gain adjustment, technicians can quickly capture clear ultrasonic waveforms.

Multiple signal filtering and waveform storage functions are integrated to record inspection data for traceability. The device works with a wide range of ultrasonic probes to implement thickness measurement and defect detection on steel, aluminum, alloys and composite materials.

Common application fields include aerospace, power equipment, petrochemical pipeline inspection, machinery manufacturing, railway and metal processing. It is widely used to check weld seams, castings, forgings and structural components to avoid safety hazards caused by internal defects.

Long battery runtime supports all-day field testing. Robust construction provides shock and dust resistance, meeting the demands of continuous outdoor nondestructive testing tasks.
