Model NRF50 Electronic Personal Dosimeter

WiFi-Enabled, Oversized Digital Display

NRF50 Electronic Dosimeter by Fuji ElectronicsFor X-ray and Gamma Radiation, Personnel Monitoring

This EPD utilizes Wi-Fi for remote monitoring systems. An easy connection to computer via Bluetooth allows users to continuously monitor personal dose, high stress work enviroments. The dosimeter features a large visual display for convenient viewing and a red emergency call control to notify safety management personnel of emergency incidents.

The NRF50 Electronic Dosimeters offer a modern alternative to traditional electronic dosimetry in nuclear facilities. By providing real-time dose monitoring and the latest, innovative technology, users have amazing communication capabilities and are able to make immediate adjustments to reduce their exposure and minimize health risks.
