The DCT10-RS is a ventilated, guarded ionization chamber for CT dosimetry (CTDI/DLP). It provides a uniform response across its 100 mm active length and uses a triaxial LEMO connector for low-noise, stable readout. Supplied with a calibration certificate, it operates with the DOSIMAX plus A HV electrometer; high voltage must be enabled for ion chamber measurements.
