The DOSIMAX plus A HV is a portable electrometer for QA and acceptance of X-ray generators. It measures dose, dose-rate and exposure time simultaneously, featuring autoranging, auto reset, and auto power-off after 10 minutes of inactivity. It operates with RQA and RQM semiconductor detectors and the external DCT10-RS CT ionization chamber.
Key applications
- Acceptance and constancy QA in radiography, fluoroscopy and mammography
- CTDI/DLP measurements using DCT10-RS
- Routine dose/dose-rate/time checks on pulsed or HF generators
- Training in measurement procedures and patient-safety practices
