Connect your iPhone with a Thermo Scientific RadEye Personal Radiation Detector (PRD / PRD-ER) or Spectroscopic Personal Radiation Detector (SPRD / SPRD-GN). The RadEye Mobile App provides a virtual front screen of the RadEye instrument itself providing visibility when the RadEye is out of reach or packed away. The App provides readings, alarms, event logging, and reachback for the RadEye field user.
