Hofmann Selector M

The diagnostic X-ray generators SELECTOR HOFMANN M, SELECTOR MD and SELECTOR D are representative of a new line of converter generators, using a high frequency converter to generate the X-ray tube voltage.

Microprocessor control circuits the control panel and all functions of the generator. 

Advantages over previous technologies:

  • Very good reproducibility of the exposure parameters
  • Very fast reactions when shooting in the millisecond range
  • Post-indication of the actual exposure parameters
  • Diverse opportunities for organ programming
  • Independent error display in case of failure

X-ray tubes

HOFMANN X-ray generators can operate X-ray tubes of all available manufacturers. If you are replacing a generator, you can exchange any discarded X-ray tube. When new systems are set up, you are free to choose the best price tube type for each specific application.
