The FLIR identiFINDER R425 is the next generation of the most deployed radionuclide identification device (RID), offering 360-degree coverage so you can locate and measure gamma and neutron radioactive sources with confidence. It builds on FLIR’s trusted algorithms with advanced heuristics and hybrid identification techniques. With the familiar identiFINDER user interface and 3-button control, you can operate the R425 quickly, communicate results, and take command of any situation, in any environment, remotely. When other systems fail in extremely high gamma fields, the FLIR identiFINDER R425 provides pinpoint accuracy and remains fully operational. The identiFINDER R425 goes the distance with balanced ergonomic design, unparalleled ruggedness, flexible power management, and usability. The R425 provides an ideal balance of size, weight, and performance for various missions including surveying, emergency response, and environmental monitoring.
Building on a legacy of tried and trusted performance
BETTER DETECTION IN ALL DIRECTIONS
New cubic detector design, sourceless stabilization, advanced heuristics, and hybrid identification techniques enable high performance detection in all directions; 3x more sensitive gamma and 2x more sensitive neutron detection
POWER THROUGH YOUR MISSION
IP67-rated, ergonomic design is 15% lighter than previous generations, while the exceptional 12-hour battery life provides the right balance for a variety of missions
SITUATIONAL AWARENESS AND SUPPORT WHEN YOU NEED IT
Remote data viewing, operation, and reach back is made possible through communication features including dual USB-C ports, FLIR's trusted web interface, the FLIR RAD Mobile Application, and a universal API that enables integration with user deployed networks
