Proto’s iXRD Mini features a compact and portable self-contained control unit. With integrated high-voltage supply, x-ray tube cooling, motor control, and system electronics, this system provides everything you need to run measurements safely and reliably. Additional safety features include external ports for interfacing to an enclosure or barrier and beacon lights indicating when the shutter and x-ray are on.

EASY and CONVENIENT residual stress measurements

The iXRD Mini is the perfect system for basic residual stress measurements. A high-performance goniometer maintains ASTM E915 accuracy in a low-maintenance design. The manual focus pointer enables accurate positioning of the goniometer in complex geometries. The automated focus pointer provides convenient focusing of large residual stress maps. A wide variety of x-ray beam apertures are available, including round 0.5, 1.0, and 2.0 mm options and rectangular 0.5x3, 1x3, and 2x5 mm options. High stress standards, zero stress powders, and RA standards ensure accurate results. Rapid movement of the z-range is accomplished with easy-adjust locking handles.
