CRC®-77tHR Dose Calibrator


The CRC®-77tHR’s performance and reliability have been designed to meet the unique and demanding needs of the high-activity isotope manufacturing and radiopharmaceutical production environments.
The software is designed for rapid repeatable measurement functions often required in production, and includes a fully automated Quality Assurance Program. Hardware is carefully designed to minimize the impact of high radiation fields upon electronics. A touch screen user interface provides a user friendly and efficient workflow.
Some features include a high activity range of over 400 Curies for Tc-99m, USB/PC Communications, and pre-defined communication protocols for fast and easy system interface.
Capintec offers a full line of related products to safely use the CRC-77tHR within your hot cell or hood environment.
