RTI CT Ion Chamber


CT Ionization Chamber for use with Piranha, Cobia Flex, or Cobia Sense.

The RTI CT chamber is intended for CTDI and dose length product measurements on CT scanners in a phantom or free-in-air.  The 10 cm chamber fits into standard phantoms used for CTDI measurements.
It fulfills applicable parts of the IEC 61674 standard for diagnostic dose meters. Thereby it is compatible with IEC 61223-2-6 and 66601-2-44 for applicable CT dosimetry.

The chambers comes with RQT9, 120 kV, W/Al + 0.25 mm Cu as standard calibration.

Please specify on the order if you would rather have another calibration.
Note: The RTI Chamber Adapter is also required.

All prices include freight cost. Pricing does not include Applicable Taxes or Customs Fees.
