The Altek Scientific and Industrial Group amalgamates more than ten companies specializing in the field of manual and automated ultrasonic and eddy current inspection.
Altek, Altek-Service, Torgovy Dom Altek, NPG Altek, Altek-Science and others engage in scientific research and experimental design work, development, manufacture and introduction of PELENG family of flaw detectors and PELENG-AUTOMAT computerized freight car wheels ultrasonic flaw detection complexes
The core of the team comes from researchers and the engineers with a wide range of experience in the field of non-destructive inspection. The team carries on large-scale scientific research and experimental design work on creation of nondestructive inspection instruments utilizing cutting edge instrument making and non-destructive testing technologies.
For over 10 years Altek Group has been responsible for manufacture of an appreciable share of non-destructive inspection instruments currently used in Russia and CIS countries.

PELENG 103
- for oil and gas industry (BCH-012 and other directions for inspection of pipelines including those of polythene)
- for shipbuilding industry (inspection of welded seams and parent metal of steel, aluminum and titanic ship hulls)
- for acceptance inspection of railway axles and wheels (according to РД32.144-2000 and accompanying documents)
IMAGING INFORMATION ON SCREEN
- A-scan
- B-scan (inspected cross-section visualization)
- W-scan (image of beam paths indicating flaw location)
- flaw characteristic (coordinates, equivalent area or diameter, detectability factor, signal amplitude). The highest signal is highlighted by an automatic measuring mark
- measuring any signal parameters in manual mode (manual measuring mark)
- simultaneous display of two gates each capable of operating by echo, through transmission or mirror- through transmission methods
- automatic flaw light and audio alarms
AUTOMATIC MODES
- scan duration can be set automatically by flaw detector depending on gate duration
- setting of ultrasonic oscillation velocity depending on material inspected and angle of probe
- compensation of emission pulses repetition frequency
- semi-automatic mode of depth meter and sensitivity
SERVICE MODES AND FUNCTIONS
- SCREEN FREEZE freezing all signals on the screen
- ENVELOPING all received signals remain on the screen
- ZOOM viewing parts of A-scan scaled-up
- RADIOSIGNAL viewing signal undetected
- CURVATURE CORRECTION automatic curvature correction of object surface when calculating flaw coordinates
Mode features:
- frequency range to 100kHz, test
- dynamic and static mode
- saving test record in flaw detector's memory and sending it to PC
THICKNESS METER MODE 
- resolution up to 0.01 mm
- minimum thickness measured 0.8 mm
- measuring by first back-wall signal or by two back-wall signals
- measuring thickness of coating
NON-VOLATILE MEMORY
- flaw detector memory may keep records of A-, B- scans, inspection report (as a table), thickness meter report
- flaw detector memory can contain up to 400 settings
- pass-code protects settings against unauthorized removal or alteration of parameters
- to use multi-step test, settings can be combined into blocks. Switching between settings within a block is done by pressing one button.
- option to couple flaw detector to PC and store inspection results in a database
INTEGRATED GENERALIZED DGS DIAGRAM MAKES IT POSSIBLE
- to tune flaw detector to detect flaws of present equivalent size (equivalent area or equivalent diameter)
- automatically identify equivalent area or equivalent diameter for any flaw detected. To tune using a side drilled back-wall or focusing surface as reflector
- The reflector may have any dimensions and be located at any depth
- automatically adjust time varied gain (TVG) or curvilinear threshold for large-size objects inspection
