The identiFINDER® R225 is a rugged, pager-sized Spectroscopic Personal Radiation Detector (SPRD). The R225 features a single 18mm cubic CsI detector with SiPM (G/GN) providing exceptional sensitivity and identification capability. There is also an option for an LaBr(Ce) spectroscopic detector (LG/LGN) for ≤3.5% resolution. The device features the familiar three-button control common to all identiFINDER products. The R225 provides ANSI N42.48 SPRD compliance, as well as MIL-STD 810G (Salt Fog) compliance.
