High-Resolution Spectroscopic Personal Radiation Detector
identiFINDER R300

The FLIR identiFINDER R300 is the world’s highest performing, pager-sized spectroscopic personal radiation detector (SPRD). It provides continuous detection and full threat identification (ANSI N42.48 library). The simple two-button user interface facilitates expedited threat response. Visible, audible, and tactile alarms rapidly alert the operator via the easy-to-read color display. On-board Bluetooth, web server, and GPS technologies make interagency communication easier than ever. The R300 is ideal for belt-worn passive-scanning, security checkpoints, border patrol, and first response.
