Core Operations and Capabilities

Evident develops and integrates inspection technologies that span across multiple physical testing modalities. The organization provides both off-the-shelf portable instruments and custom-engineered automated inspection equipment. Its engineering teams assist clients in addressing complex testing constraints, such as inspecting specialized composite geometries, handling extreme thermal environments, or automating inline production quality control.

The primary focus of Evident's technology centers on identifying material flaws—including delamination, voids, stress cracking, fatigue, wall thinning, and inclusions—across metals, plastics, alloys, and composite materials.

Key Testing Modalities and Products

Evident organizes its product portfolio into distinct categories based on inspection physics, sensor design, and level of automation.

1. Ultrasonic Testing (UT) & Phased Array Ultrasonic Testing (PAUT)

Ultrasonic testing utilizes high-frequency sound waves to measure material thickness and detect internal structural anomalies. Evident manufactures portable instruments, multi-element probes, and software platforms for complex acoustic analysis.

• Phased Array Flaw Detectors: Advanced instruments such as the OmniScan series (including OmniScan X4) that utilize multi-element transducers to electronically steer, focus, and sweep acoustic beams through test objects. These systems generate high-resolution cross-sectional images (S-scans and C-scans) for weld inspection, composite mapping, and structural testing.
• Ultrasonic Thickness Gauges: Precision measuring units, such as the 39DL PLUS and 72DL PLUS, engineered to measure remaining wall thickness on corroded pipes, boilers, pressure vessels, and thin single- or multi-layer materials.
• Transducers and Phased Array Probes: A catalog of over 5,000 standard and custom transducers, ranging from single-element contact, immersion, and delay-line probes to flexible phased array arrays that conform to curved geometry on aircraft parts or piping.

2. Eddy Current (EC) and Eddy Current Array (ECA)

Eddy current technologies utilize electromagnetic induction to detect surface and near-surface flaws in conductive materials without requiring paint or coating removal.

• Eddy Current Instruments and Probes: Portable flaw detectors paired with a portfolio of over 10,000 standard and custom probes (derived from heritage brands like Nortec). Used extensively for surface crack detection, fastener hole inspection on aircraft fuselages, and conductivity measurements.
• Tubing Inspection Probes: Specialized probes using eddy current, remote field testing (RFT), magnetic flux leakage (MFL), and internal rotating inspection systems (IRIS) ultrasound for evaluating heat exchangers, steam generators, and industrial boiler tubing.

3. Remote Visual Inspection (RVI)

RVI solutions allow technicians to visually examine internal cavities, narrow bores, turbine engines, and high-hazard enclosures without disassembling equipment.

• IPLEX Series Video Borescopes: Portable videoscopes (such as the IPLEX GX, G Lite, and IPLEX One) featuring flexible insertion tubes, high-definition camera sensors, motorized articulation, stereo measurement capabilities, and 3D modeling tools to measure flaw dimensions inside turbines, engines, and piping systems.

4. Elemental Analysis and Material Verification

• X-ray Fluorescence (XRF) Analyzers: Handheld and inline spectrometry instruments used for Positive Material Identification (PMI), alloy verification, scrap sorting, and environmental screening by delivering element-by-element composition readouts.

5. Bond Testing

• BondMaster Systems: Specialty instruments and probes (including pitch-catch, mechanical impedance analysis, and resonance probes) designed to evaluate composite structures, honeycomb sandwich panels, and metal-to-metal bonded joints in aerospace and automotive applications.
