Hofmann Selector MD

Powerful high-frequency X-ray generator for office and clinic diagnosis. The high operating comfort guaranteed for optimal X-ray and clinical practice.

The heart of all Hofmann DMT X-ray systems is the Selector MD. The multi-processor-controlled high-frequency generator is characterized by very short exposure times, simple operation and fast control of high voltage and tube current. The modern automatic exposure control ensures constant film density with exact reproducibility of the recording data. Another plus: the organ-programmed recording technology.

Features Selector MD

  • Shortest switching time 1 millisecond
  • Exact reproducibility of the data recording
  • Optimum protection tube
  • Intuitive control panel
  • CE marking CE0125
