The lightweight ergonomic unit supports automatic transducer calibration, dual-gate measurement and waveform storage. It adopts high-resolution display with minimum 60Hz refresh rate, and passes strict vibration and temperature adaptability tests to adapt to workshop and field inspection environments. Built-in comprehensive data logging function supports waveform saving and data export. Widely used in welding inspection, pipeline and forging testing, it serves as reliable inspection equipment to guarantee structural safety of industrial components.
Description
Epoch 4 GE portable ultrasonic flaw detector is a classic digital NDT instrument developed for on-site non-destructive testing, widely deployed in petrochemical, power, machinery manufacturing, shipbuilding and pressure vessel industries. Designed according to international NDT standards and GE industrial instrument specifications, this flaw detector utilizes ultrasonic pulse-echo principle to identify hidden internal defects which cannot be observed by visual inspection. Every unit undergoes complete factory calibration, continuous operation aging and electromagnetic compatibility testing to ensure stable measuring repeatability under complex outdoor and factory working conditions.
The instrument integrates advanced signal processing architecture, supporting selectable spike excitation and adjustable square wave pulser. Square wave technology greatly improves penetration capacity for thick workpieces and high-attenuation materials such as cast iron and large forgings, while customizable narrowband filters effectively lift signal-to-noise ratio under high gain conditions. Its analog bandwidth reaches up to 25 MHz, enabling accurate inspection for thin-wall components. Multiple detection modes including pulse-echo, dual-element and through-transmission are available to match different probes and inspection requirements.
With compact rugged housing and only 2.6kg weight, the equipment is convenient for handheld long-time field operation. Users can choose high-brightness ELD or LCD display, supporting full-screen and split-screen view, waveform freeze, peak memory and RF signal display. The built-in dual measurement gates support echo-to-echo thickness measurement and defect depth positioning. Multi-level alarm functions can be triggered when echo amplitude exceeds preset thresholds, helping inspectors quickly capture abnormal signals during scanning. The intuitive color-coded keypad allows rapid parameter setup without complicated operation procedures.
Powered by high-capacity rechargeable NiMH battery, the instrument supports long-duration continuous field inspection. Large-capacity internal memory stores abundant A-scan waveforms and inspection records. Matched with optional GageView Pro software, stored data can be transmitted to PC for sorting, report editing and archiving, facilitating standardized quality management. Standard communication interfaces support data exchange with printers and external displays.
When original testing equipment ages or malfunctions, Epoch 4 can be adopted as a compatible replacement unit. Unified operation logic reduces training cost for inspection technicians. Reliable defect detection helps enterprises discover structural risks in advance, avoid equipment failure and safety accidents caused by internal material defects. It can complete welding quality assessment, pipeline corrosion inspection, forging defect screening and regular equipment safety evaluation tasks.
Combining powerful ultrasonic performance, portable mechanical design and complete data management functions, Epoch 4 GE ultrasonic flaw detector remains a cost-effective preferred solution for industrial non-destructive testing. It provides dependable technical support for quality control and structural safety assurance of industrial equipment.
