The FLIR identiFINDER R440 is a lightweight, sourceless radioisotope identification device (RIID) that can be operated with one hand and is IP67-rated to survive tough missions. Not only does the 2x2 NaI detector deliver sensitive and fast detection, but it also provides accurate identification during secondary screening. The new 360° EasyFinder™ Mode expedites decision-making to keep you safe.
Highly Sensitive 2x2 NaI Detector
Detects radiological threats from farther away, behind heavier shielding, and with better resolution than similarly sized RIIDs.
Drop-tested up to 1 meter and built to survive rigorous missions, with completely enclosed crystal and IP67-rated enclosure that protects against dust and water immersion up to 1m.
State-of-the-Art User Features
360° EasyFinder Mode pinpoints and instructs the operator on the exact location of a radiation source to keep responders and the community safe.
1 year factory maintenance suggested, not required
Absorption of EM gamma (NaI) or gamma and neutron emissions (NaIL)
Detects neutron or gamma radiation emitted from natural occurrences in the environment, special nuclear material, industrial, or medical material
