HST-X04HST X04 Scanner

Olympus Logo

The Olympus HST-X04 time-of-flight diffraction (TOFD) manual scanner offers an efficient, low-cost, and versatile weld inspection solution.


  • Manually deployed single-axis scanner for use on plate, pipe, and curved surfaces
  • Applicable to pipes, pressure vessels, storage tanks, and structural components
  • Operates in any orientation, either on flat surfaces or on pipes up to 51-mm (2 in.) OD.

Data acquisition

  • Permanent record of the results with the OmniScan®
  • Ideal for position-related A-scan, B-scan, and echo-dynamic scan data collection
  • Suitable for any system with 2 UT channels

Scanner Kit Components

  • Scanner with 150-mm frame
  • Two 10-MHz (3-mm element diameter) CentraScan™ composite TOFD probes offering signal-to-noise ratio improvement over conventional UT probes
  • Three sets of ST1 wedges with carbide wear pins and irrigation holes for 45º, 60º, and 70º operation
  • Two LEMO®-Microdot® transducer cables 2.5m long
  • Two LEMO®-to-BNC adapters
  • Spring-loaded, friction-driven, and water proof Mini-Wheel encoder for X-axis or Y-axis data encoding
  • Brackets for flexible encoder positioning
  • Additional 250-mm frame for wider probe center separation
  • Foam-padded carrying case

This HST-X04 Scanner kit can be further configured to fit the broad range of Olympus TOFD and pulse-echo probes and wedges, including the composite product line.


  • Encoded linear-scan (one axis) for TOFD or pulse-echo inspections with appropriate yoke
  • Water proof spring loaded encoder with rubber wheel for maximum adherence on inspected surfaces
  • Compact, light and versatile
  • Cost-effective
  • Durable construction
  • Can fit a full range of probes and wedges, including the CentraScan™ composite product line
  • Probe center separation (PCS) fully adjustable from 17 mm to 180 mm
  • Low-profile frame for use in constrained areas
  • Tool-free quick release of wedges and probe holders
  • Encoder resolution: 12 step/mm
  • Compatible with the OmniScan, the TomoScan FOCUS LT (with optional adapter), and other instruments using the appropriate encoder cable (not included).
