The identiFINDER® R440 is a lightweight, source-less radionuclide identification device (RID) that delivers sensitive detection and fast results for routine survey or secondary screening response missions. The R440 is available with NaIL, NaI, LaBr and CLLBC detector options to respond to radiological threats from farther away, behind heavier shielding, and with better resolution than similarly-sized RIDs. The extended energy range provides neutron indication in the NaI (G) version. Its light weight makes single-handed operation easy during extended operations, while the IP67-rated enclosure is built to survive. The bold, easy-to-read interface with 360° EasyFinder™ mode expedites decision-making to keep personnel and the community safe. Hot swappable batteries facilitate continuous operation on extended missions and the ability to charge batteries outside on the instrument while the instrument is on standby ensures instant readiness in the response vehicle.

Power Through Missions

  • Higher Performance In a Rugged Form Factor

    Adding to the advanced spectroscopic algorithm and sensitivity of the original R440, the new ruggedized R440 adds optional, proven, higher resolution detection capability.

  • Ability to Power Through Missions

    Power flexibility with the new hot swappable batteries means the new R440 will go the distance and complete the mission with you.

  • Situational Awareness When You Need It

    When threat detection occurs, getting results communicated as quickly as possible is critical. The new R440 makes communications easier than ever before, no matter the method.
