The 10XF-3CT is a cylindrical air ionization chamber designed for Computed Tomography Dose Index (CTDI) and Dose Length Product (DLP) measurements on CT scanners.
It provides a flat energy response across its entire active length, ensuring homogeneous and reproducible beam sampling for high-precision QA measurements.
Constructed from C552 conductive materials, the 10XF-3CT features uniform sensitivity, integrated guarding, and comes with an individual calibration certificate for traceable accuracy.
With proven stability and compatibility with IBA electrometers such as MagicMaX and DosimaX, it is the standard reference chamber for CT beam quality from 100 to 150 kV.
