Type: CRC-25R live meter measuring instrument known as isotope activity
Origin: United States C CRC
1, CRC-25R is a common isotope measuring instruments, used for the Hospital Department of Nuclear Medicine, etc.;
2, CRC-25PET is dedicated PET instruments used to measure commonly used PET isotopes;
Which CRC-25R is a meter of living a dedicated nuclear medicine intelligent precision measuring instruments, their performance and functionality h***e reached the international advanced level, is the world's most cost-effective products, the user has been all over the world, domestic users h***e on the 1000; this instrument by the probe and the host composition, the amount of product automatic conversion, automatic measurement, automatic tracking of the deduction at the end of the performance is very stable, well received by users.
CRC-25R living Meter CRC-25R living as a CRC-15R meter upgrade products, was inherited from the previous style, stable, convenient and fast measurement speed. Using the most advanced integrated circuit technology and shielding of the ionization chamber, to provide you with high-speed, precision and some other measurement of activity levels and prepare doses of the functionality required. Technical specificati*** and performance: Configuration:
CRC-25R Features:
