NOESIS - Acoustic Emission Data Advanced Analysis Software


See Mistras Group Hellas' NOESIS version 5.0 software for Advanced Analysis of Acoustic Emission Data, utilizing Visual objects and implementing Supervised Pattern Recognition, Unsupervised Pattern Recognition and Neural Networks and Advanced Waveform Management.

New in this version is the Live-SPR (Data Classification and Processing During Acquisition).


AE Pressure Vessel Inspection with MONPAC


MONPAC is an Acoustic Emission based expert system for evaluating the structural integrity of metallic pressure vessels, spheres, columns and tanks. MONPAC consists of AE test procedures and evaluation criteria and enables 100% inspection of the vessel during one pressure test. MONPAC can be applied during First Hydrotest of a new Pressure Vessel according to ASME-V Part 12, Requalification Hydrotest of a used Pressure Vessel, On Line Pressurization (in-service with working fluid).


Multichannel Acoustic Emission Systems


Physical Acoustics offers a complete multichannel product line, ranging from products with two channels, to units with multi-hundred AE channels. Systems can be synchronized to each other to accommodate an expanded number of channels. Our multichannel product's capabilities allow users to simultaneously monitor and record AE frequencies. Multichannel products incorporate specialized AE boards, designed to accommodate use of multiple AE sensors, for more comprehensive analysis of the asset.


Ultrasonic C-Scan / Imaging Systems


MISTRAS Group, Inc., offers a full line of Ultrasonic (UT) products and inspection systems designed to fit the needs of any testing market. From immersion systems and large-scale scanners, to single or multichannel systems; UT boards and software, to system scanners and accessories.

New AEwinPost v2.0

The new version of the post-processing Acoustic Emission Data software is released.

Thickness Gages: Simple Operation, Rugged, and Reliable


We are the leading source of thickness gages for the accurate measurement of nearly any material. Thickness gages include a wide range of features available for enhanced gage performance. Ultrasonic thickness gages can measure virtually most materials such as plastics, metals, metal composites, rubber and internally corroded materials.


OmniScan MX2


The OmniScan MX2 now features a new phased array module (PA2) with a UT channel, and a new two-channel conventional ultrasound module (UT2) that can be used for TOFD (Time-of-Flight Diffraction), as well as new software programs that expand the capabilities of the successful OmniScan MX2 platform.


UTIA - Ultrasonic Imaging and Analysis Software


Mistras Group Hellas' UTIA software for advanced Ultrasonic Data Analysis provides the user with a complete set of tools for manipulating / post-processing, viewing and exporting ultrasonic A/B/C-Scan data. These tools allow for easy viewing, statistics, composite C-Scan images, 3D C-Scan images and image/data export to any Windows application. Also support advanced waveform management.


Ultrasonic Flaw Detectors


Ultrasonic flaw detection is widely used to detect and characterize hidden internal defects in engineering materials such as metals, plastics and composites. High frequency sound waves reflect from cracks, voids and other material discontinuities, producing distinctive echo patterns.


Acoustic Emission AEGIS s/w for W/T BladesResearch & Development


On-going European and Domestic research programs include Wind Turbine Blade assessment by Acoustic Emission, concrete damage and properties assessment by Acoustic Emission and Acousto-Ultrasonic techniques. See also information about in-house research and development.
