identiFINDER R425 Radionuclide Identification Device
The FLIR identiFINDER R425 is the next generation of the most deployed handheld radionuclide identification device (RID), the Identifinder R400. The radiation detector offers 360-degree coverage so you can locate and measure radioactive sources with confidence.
Built on FLIR’s trusted algorithms with advanced heuristics and hybrid identification techniques, the R425 maintains the familiar identiFINDER user interface and 3-button control.
When other systems fail in extremely high gamma fields, the FLIR identiFINDER R425 provides pinpoint accuracy and remains fully operational. The identiFINDER R425 has a balanced design, unparalleled ruggedness, flexible power management, and intuitive interface allow the detector to be operated quickly and effectively.
The R425 provides a balance of size, weight, and performance for the detection of radiation in a variety of missions including surveying, emergency response, and environmental monitoring.
