    Description

    identiFINDER® R225

    FLIR

    The FLIR identiFINDER® R225 is a compact, rugged spectroscopic personal radiation detector (SPRD) that delivers fast and accurate radiation identification in high-stakes environments. Building on the proven success of the R200, the R225 features a brighter, full-color display that remains visible even in direct sunlight or when viewed through polarized eyewear—critical for outdoor or tactical operations.

    Engineered with real-world feedback from field personnel, the R225 offers multilingual support, an improved ergonomic holster that allows full screen visibility while holstered, and extended battery life exceeding 30 hours. Designed for first responders, hazmat teams, law enforcement, and border security, this device ensures rapid situational awareness and safe decision-making.

    With built-in Bluetooth®, Wi-Fi®, and GPS, the identiFINDER R225 enables remote data access and live transmission, ensuring seamless communication with command centers and CBRNe specialists. The unit uses a high-sensitivity CsI detector with SiPM (G/GN) or an optional LaBr(Ce) spectroscopic crystal (LG/LGN), offering high-resolution performance and ANSI N42.48 SPRD compliance.

    Features

    • A single 18mm cubic CsI detector with SiPM (G/GN)

    • LaBr(Ce) spectroscopic detector optional (LG/LGN)

    • ZnS(Li) panels for Neutron Detection (GN/LGN)

    • Single-hand operation via 3-button control

    • ANSI/IEEE Compliant N42.32, N42.48, and N42.42

    • Color screen

    • 30+ hour battery life with hot swappable back-up feature

    Fast Frontline Detection and Response

    Outstanding spectral ability to enable fast front-line detection and response

    • Belt-worn gamma and neutron detection and gamma identification.

    • Technologically advanced SiPM with Csl to provide <7.5% resolution or SiPM with LaBr to provide <3.5% resolution.

    • Field-proven and trusted template matching algorithms characteristic and present in the entire identiFINDER family of products.

    Wear with Confidence in the Harshest Environments

    Survives tough missions so you can wear with confidence

    • IP67 rated for use in harsh environments or temporary submersion during decontamination

    • MIL-STD 810G (salt/fog) compliant

    • Automatic calibration, stabilization, and no user maintenance required

    Provide Critical Information in Real Time

    Low training burden for quick field adoption

    • Easy to interpret results and interface designed to align with typical operating procedures

    • Built in communications and a robust API enable integration with user deployed networks. ANSI N42.42 data output is standard.

    • Ability to monitor and control remotely using the mobile app (iOS & Android).
