The New Standard For Speed and Accuracy in Measuring PET Isotopes

The new CRC®-25PET Dose Calibrator meets the demands of your Nuclear Medicine/PET Department with a host of new features for optimized usage; including USB capabilities, SD flash cards for software upgrades, chamber plug-and-play, enhanced remote functionality, and more.

All nuclide data is entered via the custom keyboard that includes 9 user-definable keys. Four reference sources are stored in memory, that are automatically decay-corrected for today’s time and date. Its space efficient design allows for a large, easy to read display.

Dose calibration quality control tests and self-diagnostics are built in; along with automatic zero and background subtraction, making the CRC®-25PET extremely easy to use. Optional printers enable the CRC®-25PET to print full size records and patient tickets with peel off labels for vial and syringe identification.

Reduced chamber pressure and increased bias voltage increases the maximum activity range for high energy PET isotopes. A sophisticated microprocessor chip platform expands control features and improves the speed of activity measurements.
