Features
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) with high accuracy. The CRC -25W now features a helpful chamber plug-and-play capability.
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. Perform nuclide and Daily Test selections hundreds of feet away from the CRC -25W read out unit with our new remote capabilities.
Count on Capintec not only for excellence in energy measurement, but for our unsurpassed customer service, training and support!
