AERIS

Portable gamma spectrometer for on-site air filter analysis

Rugged portable gamma spectrometer that analyses radioactive contamination on air filters and cartridges right where they are collected, in fixed or mobile set-ups. A shielded NaI(Tl) detector with SiPM identifies radionuclides and quantifies activity without sending samples to a laboratory; pre-loaded efficiency curves and a guided start let non-specialists measure correctly.

Detector type: NaI(Tl) 2 × 2 in with SiPM and digital MCA2
Energy range: 30 keV–3 MeV2
Weight: 12 kg (excl. transport case)2
