Detective DX1-TS
Portable HPGe spectrometer for in-situ measurements
Portable, all-inclusive high-resolution gamma spectrometer for in-situ measurements. It collects spectra stand-alone in the field or under computer control via USB, Ethernet or Wi-Fi with applications such as MAESTRO-Pro (included), GammaVision and ISOTOPIC. Physically identical to the Detective DX1, but without the automatic isotope identification applications; it can be upgraded at the factory.

- Energy resolution at 122 keV
- ≤1630 eV FWHM (warranted at optimum settings)1
- Energy resolution at 1.33 MeV
- ≤2.0 keV FWHM at 1,332 keV (warranted at optimum settings)1
