30 cm Ionization Chamber for Free-in-air Measurements
The CT Chamber 30 cm is a cylindrical pencil-shaped air ionization chamber specially developed for free in air measurements on wide beam CT scanners. The CT chamber 30 cm is intended for measuring and monitoring the exposure output level of CT scanners when the beam width is 4 cm or wider.
The chamber can be connected via Chamber Adapter to the Piranha or Cobia to measure CTDI.
The CT Chamber 30 cm fulfils relevant parts of IEC 61223-2-6, and IEC 60601-2-44
Art. No 9705135-00
