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

The R225 comes with key features built on feedback from its predecessor, the identiFINDER R200, including multi-language operation. The display has been upgraded for increased brightness and added color for visibility in sunlight and through polarized sunglasses. The holster has been modified to provide quick access to the device and for the screen to be fully visible while holstered. The battery can run for over thirty hours with hot-swappable spare batteries, Bluetooth, Wi-Fi and built-in GPS ensure remote data viewing.
