NRF50 Electronic Personal Dosimeter

WiFi-Enabled, Oversized Digital Display

For 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. AlaraCast optional software is available for remote monitoring.
