Desktop Retained Austenite Analyzer — AreX D by GNR
The AreX D is a benchtop retained-austenite analyzer built to ASTM E 975-13. It measures down to 1% by volume within minutes, weighs 37 kg and is air-cooled, so no cooling water is needed.

AreX D — size and installation
490 × 550 × 360 mm, 37 kg, 110/220 V 50/60 Hz. The X-ray tube is air-cooled, so no cooling water is needed.
Used for heat-treatment quality control and gear/bearing parts — GNR’s example measures three points on a gear tooth (pitch diameter, top land, top corner).
