Gamma ray radioactive detector FD-808

FD-808 Gamma ray radioactive detector&water detection instrument

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.
