Unfors has released Direct X-ray Ruler (DXR), a new tool to meet the needs of real-time checks of the light and radiation field alignment.
The pocket-sized, fully automatic device operates down to 0.5 mAs and gives an objective, reproducible and immediate read out. It is powered on by exposing the meter. Features include auto reset and auto power off. Unfors says there is no need to adjust the light field to a square phantom before making an exposure.
