Automatic Test Range Calibration
• It is faster, more accurate and easier than
manual calibration.
High End, Accurate & Convenient Flaw Detection
Pulse Repetition Frequency (PRF)
• It is possible to set PRF as low as 4 Hz to
eliminate phantom / ghost echoes while
testing large forgings etc…
High End, Accurate & Convenient Flaw Detection
Simultaneous Display of Four Measurement Values
• Selection of upto four measurement values for
simultaneous display helps the operator in
quick interpretation.
High End, Accurate & Convenient Flaw Detection
Wide Frequency Range
(250 KHz to 20 MHz)
• Frequency down to 250 KHz (0.25 MHz)
enables testing of highly attenuative materials
like composites, austenitic stainless steel etc..
• Probe with frequency up to 20 MHz on higher
side can be used for checking low thickness
jobs and for enhanced sensitivity.
