Quality assurance devices and test tools are essential whenever X-ray radiation is used, which is typically in a laboratory, dentistry or medical facility. At the heart of the quality assurance (QA) set up in any environment where X-ray emitting devices are deployed is an accurate X-ray measurement system. This is complemented by other X-ray test tools, and often external probes and accessories that tailor the QA meters to the specific requirements of the situation.
