Fulcrum: definitive isotope ID in 8 pounds

At 8 × 5 × 6 inches, the Fulcrum is the smallest mechanically cooled HPGe system available. Onboard acquisition and analysis put gamma-ray spectroscopy, isotope ID, and quantification in the hands of field teams at any experience level.

Fulcrum
  • Superior Resolution: FWHM < 950 eV at 122 keV; < 1.9 keV at 1332 keV
  • Continuous field operation via battery hot-swap
  • 2-hour cool-down to operating temperature
