The FIDELIS high precision activity meter is used by many metrology institutes in the world as a national standard device due to its excellent performance. At least 60 nuclides were calibrated strictly by the National Metrology Institute of the UK. Powerful software with good man-machine interface enables users to update the latest data released by the UK National Metrology Institute.
1, the instrument factory is strictly calibrated by the British National Metrology Institute.
2. The software is compatible with Windows XP and Windows 7
3, at least 60 kinds of nuclides are strictly calibrated, and users can customize them according to their needs.
4, the nuclide calibration value is stored on the ionization chamber and does not depend on the reader. User upgrade commitment: New Nuclide containers and new nuclides can be modified by published calibration data.
5, full automatic self test, measurement data can be exported to the EXCEL table to facilitate the use of nuclear medicine management system.
6, USB communication interface, can be connected to desktop computers or notebooks, and can also be connected to the printer for data printing.
