Spectroscopic Personal Radiation Detector

identiFINDER® R225: Stop the threat, not the team.

A pager-sized spectroscopic personal radiation detector (SPRD) for police, hazmat, customs, and security. Choose CsI(Tl) or LaBr₃(Ce), with optional neutron. Works on the belt, in vehicles, or on foot. Built-in Wi-Fi/BLE, on-board web server, and mobile app streamline the end-to-end workflow from alarm to nuclide ID to report.

Why Teams Choose identiFINDER R225?

• Faster decisions: 1024-channel spectroscopy to 3 MeV delivers on-scene IDs in seconds.
• Rugged in weather: IP67 and MIL-STD-810G (salt/fog) keep it working in rain, dust, and spray.
• Consistent UI: Classic 3-button identiFINDER controls and bright, sunlight-readable colour screen.
• Power that lasts: ≥24 h internal Li-ion plus hot-swappable CR123A backup (≥12 h).
• Standards-driven trust: Fully compliant with ANSI N42.48, N42.32, and N42.42.

Frequently Asked Questions

What detector configurations are available?
CsI(Tl) or LaBr₃(Ce) for gamma; add ZnS for neutron (GN/LGN variants).

How rugged is the device?
Rated IP67 and tested to MIL-STD-810G (salt/fog) for wet, dusty, and maritime use.

Which devices can control or view it?
Use the on-board web server over Wi-Fi or the iOS/Android app via BLE/Wi-Fi.

Does it meet recognised standards?
Yes—ANSI N42.48 (SPRD), N42.32 (PRD), and N42.42 (data). Data outputs slot into existing workflows.
