ISONIC 3505 – Portable Smart All-In-One Ultrasonic Flaw Detector and Recorder Settling a New Standard in the UT Instrumentation.

ISONIC 3505 carries the exceptionally innovative ultrasonic card with never-saturated-receiver – for the first time ever the instrument digitizes the originally received signals independently on the gain and rectification settings in every firing / receiving cycle keeping the linearity over 140 dB dynamic range. Once the single A-Scan or the sequence of A-Scans forming a record is stored into a file it may be reproduced off-line in the form desired by an operator (RF, half- or full wave rectified, FFT) at any gain level over the 140 dB range. So even in case of very significant deviation of the pre-inspection gain setting from the required value the observation and evaluation of the recorded data may be performed at the right levels without secondary scanning.

For more information please click in the link below: 

ISONIC 3505 may be operated as:

  • superior performance A-Scan set including the spectrum analyser for ultrasonic signals
  • fully featured (data capturing and enhanced post processing) standalone TOFD unit
  • CHIME system
  • general purpose CB-Scan machine for the performing of:
  • SRGW (short range guided wave) inspection and imaging also known as SRUT
  • surface / shear wave inspection and mapping
  • volume overlay incidence angle / skip corrected high resolution flaw detection B-Scan and Thickness Profile recorder
  • C-Scan machine – straight- and angle beam inspection (optional) with 100% raw data storage

Thanks to the never-saturated-receiver ISONIC 3505 is featured with the ability of individual gain control for both independent gates over the range of 140 dB separately from the rest of the A-Scan reproduced at the global instrument gain. This opens a number of new abilities such as:

  • implementing pulse echo and back echo attenuation inspections simultaneously with use of the same A-Scan whilst monitoring the back echo amplitude at the clearly visible level without affecting the sensitivity of the pulse echo inspection
  • increasing the detectability of subsurface defects for TOFD inspection through shortening the tail of lateral wave signal dynamically
  • precise materials characterization through the signal spectrum analysis independent on the instrument gain setting etc

ISONIC 3505 is fully controllable over Ethernet and featured with the hardware triggering in/out terminalsand the interface echo triggering making it suitable for use in various integrated systems

The lifetime free software upgrade policy is provided for ISONIC 3505 as for all other instruments from Sonotron NDT

ISONIC 3505 is packed into the IP 65 reinforced plastic case with no intake air or any other cooling means required. The large 800X600 pixels 8.5” bright screen provides fine resolution and visibility for all types of inspection data presentation at strong ambient light along with the optimized power consumption rate for the outdoor operation


Very Powerful Superior Performance Extremely Portable Smart Phased Array Ultrasonic Flaw Detector and Recorder with 2 Conventional UT and TOFD Channels.

ISONIC 3510 uniquely combines phased array (PA), single- and multi-channel conventional UT, and TOFD modalities providing 100% raw data recording and imaging. Along with the intuitive user interface, portability, lightweight, and battery operation this makes it suitable for all kinds of every-day ultrasonic inspections.

The new ISONIC 3510 is a successor of the very successful ISONIC 2010 instrument, which is present on the market since more than 6 years ago and became the standard in the significant number of industries around the Globe.

In the ISONIC 3510 PA modality is carried by the fully parallel non-multiplexed 32:32 electronics with independently adjustable emitting and receiving aperture, each may consist of 1…32 elements when operating one PA probe or 1…16 elements per probe in case of operating two PA probes simultaneously: there is no external splitter required for the simultaneous use of 2 PA probes.

64- and 128-elements PA probes may be used with ISONIC 3510 as well upon they are connected to the corresponding instrument’s terminals through the various miniature extenders expanding the functionality to the fully parallel 1 X 64:64, 2 X 32:32, 1 X 128:128, and 2 X 64:64 modes with no multiplexing involved (depending on the type and quantity of the extenders). The groups of PA probe elements composing the emitting and receiving aperture are freely adjustable and may be fully or partially matching or totally separated allowing the flexible managing of the incidence angles, focal distances, types of radiated and received waves including the directly reflected and the diffracted signals either mode converted or not. Each channel is equipped with the own pulser-receiver and A/D converter. Parallel firing, A/D conversion, and ”on-the-fly” digital phasing are performed for every possible composition and size of the emitting and receiving aperture so the implementing of each focal law is completed within a single pulsing/receiving cycle providing the maximal possible speed of the material coverage.

In addition to the PA electronics ISONIC 3510 carries 2 independent conventional channels for implementing of the regular UT and TOFD inspection; each conventional channel is capable for both single and dual modes of use.

The top level ultrasonic performance is achieved through the firing of PA, TOFD, and conventional probes with the bipolar square wave initial pulse with wide-range-tunable duration and amplitude (up to 300 Vpp). The high stability of the initial pulse amplitude within entire duration of the positive and negative half-waves, the extremely short boosted rising and falling edges and the automatic adaptive damping improve the signal to noise ratio and resolution allowing controlling of the analogue gain over the 0…100 dB range for each modality

As its well-known predecessors ISONIC 2010 and ISONIC 2009 UPA Scope the new ISONIC 3510 is a powerful platform for the huge number of the practical PA UT applications available for the activation at any moment. Thanks to the unique True-To-Geometry Volume Overlap Coverage and Real Time Imaging the ISONIC 3510 is suitable for the high performance inspection of the simple and complex geometry welds (butt, longitudinal, fillet, lap, corner, elbow, etc) with scanning from one or both sides simultaneously (if applicable), bolts, bridge hanger pins, wind turbine and other shafts, annular rings, flanges, railway axles and wheels, CRFP and GRFP composite panels, profiled items, and the like. The precise and easy reproducible automatic Equalizing of the Sensitivity within Entire Cross-Section / Volume of the Material is provided by the unique TCG-independent angle gain / gain per focal law compensation solution along with the DAC / TCG image normalization. Thanks to the above noted True-To-Geometry Volume Overlap Coverage and Imaging and Equalizing of the Sensitivity within Entire Cross-Section / Volume of the Material the inspection results produced by the ISONIC 3510 and its predecessors are easy interpretable and well acceptable by the UT Pros and non-Pros as well.

PA UT: Applications Store

Thanks to their unique smart, flexible, and “teachable” architecture combined with the outstanding ultrasonic performance ISONIC 3510, ISONIC 2010, and ISONIC 2009 UPA Scope have been the ideal platforms for practically unlimited number of standard and customized inspection software applications, the number of which is increasing permanently.

Each application is dedicated to the resolving of the inspection tasks related to the certain class of parts and materials to be tested (the similar shape parts varying by the overall dimensions and the dimensions of particular segments). Since the part to be inspected is outlined the scan plan is created just in few moments providing the True-to-Geometry Volume Corrected Coverage and imaging. This makes it possible to inspect complex geometry parts easily.
