CRC 25W Dose Calibrator/Well Counter

5130-3216-USED

As a combination of the popular CRC®-25R Dose Calibrator and the CAPRAC®-R Well Counter, the CRC®-25W dose calibrator provides advanced features with the speed and accuracy you need to measure activity and prepare doses. Its ion chamber is one of Capintec's time-tested, high pressure well designs capable of measuring a dose as high as 6 Ci (250 GBq) of Tc 99m with high accuracy. The CRC®-25W also features chamber plug-and-play capability.

OVERVIEW

For wipe testing, the CRC®-25W allows the user to define specific counting procedures (protocols) with trigger levels for work, patient, unrestricted areas and sealed source leak tests. The CRC®-25W also performs counting functions for wipe
tests in as little as 6 seconds at activities as low as 1 nCi. Low activities are measured with a drilled well high sensitivity Sodium Iodide (NaI) detector. The 6-channel pulse-height analyzer also provides the user with pulse amplitude discrimination, which can be used to help with radionuclide isotope identification. The chamber and counter of the CRC®-25W are combined in a menu driven, push-button interface that is easy to learn and use. Hardwired microchip control eliminates analog switches and dials, while improving measurement response time.
