Exradin Parallel Plate Chambers ensure precision in depth-dose measurements by providing uniform field lines even at low energies.


The Exradin Advantage


  • Exceptionally wide guard rings exceed 3mm widths recommended in TG-39.

  • Rigid stem allows accurate positioning of chamber.

  • Chamber vents through a flexible tube sealed to the chamber body, ideal for use in water or plastic phantoms.
