FD-808 is an intelligent portable gamma spectrometer and dose rate measurement meter, which completely conforms to GB energy response. You can read nuclear radiation strength or exposure rate directly, also quantitatively calculate contents of radionuclide like uranium, thorium and kalium through spectrogram. It has good stability, simple operation, small volume, light weight etc.

Applications:
Find underground water resource, mineral prospecting, environmental monitoring, geological survey, nuclear laboratory and so on.

Functions:

1. X-gamma radiation total amount measurement
2. U, Th, K quantitative analysis
3. Recognize radionuclide

4. Radioactive detection of environment, building materials and house decoration stuff

5. Search underground water and determine solid objects density
