crc-55tr dose calibrator
The new Capintec CRC™-55tPET Dose Calibrator gives you the ultimate features in the industry’s finest package. The CRC™-55tPET Dose Calibrator is designed to meet the demands of your department with accuracy and ease of operation. Reduced chamber pressure and increased bias voltage increases the maximum activity range for high energy PET isotopes.

The CRC™-55tPET provides a menu driven, touch screen interface that is easy to learn and use. The improved user interface contains an improved graphic color display, making operation and usage easier than ever. The unit provides 28 programmable keys. The user can select from over 80 nuclides by simply selecting the nuclide symbol on the touch screen interface.

Other capabilities include storage of reference sources in memory that automatically decay corrects for today’s time and date. Automated quality control tests and self-diagnostics are built-in with automatic zero and background subtraction making the CRC™-55tPET exceptionally easy to use.
