Thimble Ion Chambers

Strict manufacturing tolerances and waterproof construction makes these detectors ideal for dosimetry calibrations in water, air and other phantom materials.

The Exradin Advantage


  • Waterproof construction backed by five-year warranty.

  • Rugged Shonka plastic provides years of reliable use and excellent conductivity.

  • Lack of stem-effect and low leakage provides precise, consistent measurements.

  • Proven guard design stabilizes measurements and reduces settling time.

  • Homogeneous material throughout the chamber minimizes perturbation of the beam.

The A19 fits existing plastic phantom cavities and build-up caps, limiting perturbation and minimizing settling time in absolute dosimetry calibration. This chamber is characterized for TG-51 procedures.


Also available in MR compatible version.
