Gamma Spectrometer combines NaI(TI) crystal of different sizes, a photomultiplier tube, a high voltage power supply, a preamplifier and a multi-channel analyzer module mounted within a rugged housing. 

The whole system is entirely powered from the USB interface. Due to the integration of all hardware components required for a gamma spectroscopy system in one package, only one USB cable is required to connect the detector to a computer. This simplifies use and lowers the total costs of the gamma spectrometer.

The gamma spectrometer is operated with GammaPRO software package. The only requirement is that the host computer has an integrated USB high power hub or host port.

The Gamma spectrometer based on NaI detector is available with following detector dimensions:

  • 51mm x 51mm (2" x 2")
  • 63mm x 63mm (2.5" x 2.5")
  • 76mm x 76mm (3" x 3")
