Lorad SPX-300

The SPX-300 is replacing the LPX-300 model.

  • 10 to 300kV, 0.5mA to 10.0mA
  • Constant Potential Output
  • Excellent Stability and Regulation
  • Power Factor Corrected AC Input Circuitry
  • Digital Interface, Ethernet and RS-232
  • End Grounded Exposed Anode
  • Portable, Repeatable, Accurate
  • 100% Duty Cycle
  • Unparalleled Resolution Imaging
  • Liquid or Air Cooled Models
  • Penetration of up to 76mm of Fe

The SPX Series are perfectly suited for today's demanding NDT inspection requirements. SPX units are rugged, yet easy to transport and economical to maintain. They can be line or portable generator powered automatically adapting to standard input voltages to permit all day inspection under extreme conditions virtually anywhere.

The end grounded X-Ray tubes have a focal spot of 1.5mm sq. and the exposed anode allows for easy and flexible positioning of the tube head assembly. Tube ports use a low-absorption beryllium window that allows the radiographer to utilize the full spectrum of X-Ray energy. The high radiation output of the SPX systems allows for lower kV per exposure, shorter exposure times and increased film contrast for superior radiographic imaging.


The SPX microprocessor-driven control unit provides automatic warm-up and comprehensice self-diagnostic circuitry. Memory to store and recall exposure techniques is standard and the last set of exposure parameters is retained before powering down. The SPX is adjustable in 1kV and 0.1mA increments. Exposure duration can be set from 1 second to 99 minutes 59 seconds in 1 second increments.

Optional Accessories:

GUI Control Software for the SPX
GUI is specifically designed for controlling SPX series systems. As an alternative to the front panel control, the GUI will allow the user to control all necessary functions of the system from a user-friendly windows based menu. Additionally the GUI can be used as a diagnostic tool when the system is controlled via the front panel.
  • Automatic warm-up of the X-ray tube
  • Timed or Continuous Exposure modes
  • Fault and status monitor

Laser Pointer
Spellman's exclusive Laser Pointer allows pinpoint imag area targeting. The Laser Pointer projects a highly visible reference laser beam from the tubehead to surfaces up to 75 feet away, showing precisely where the central X-Ray beam will be located, providing greater efficiency and reduced set-up times.
Tubehead Stand
An optional X-Ray Tubehead Stand allows for quick set-up and provides rigid support for optimal image quality with three-axis positioning of the tubehead assembly. The stand incorporates telescoping legs, a hand wheel driven variable height adjustment and lockable hand wheel, controlling the tubehead tilt and horizontal rotation. The tubehead cradle is cushioned for secure mounting and vibration damping. A bubble-type indicator is included for quick and easy leveling of the tubehead. Black anodized aluminum construction. 35 lbs. (16kg) approximately.
Air Cooled Tube Head Assembly
The air cooled tube head assembly uses a heat sink and high volume fan to dissipate heat from the anode and typically is used in applications that do not have limited access and are not in a volatile fuel vapor atmosphere. The air cooled tube head assembly does not require the cooler unit and the associated mixing and maintenance of liquid coolant. This unit requires less user maintenance and could be considered more environmentally friendly.
