Compact multi-purpose survey meter for external Geiger-Mueller detectors, measuring count rate, surface contamination and dose rate.
The RadEye GX is part of the RadEye X Series, together with the RadEye SX for scintillation probes and the RadEye PX for proportional detectors. The GX is the version for Geiger-Mueller detectors and measures count rate, surface contamination and dose rate with the connected probe.
The display and alarm LED remain visible while the instrument is worn in its transparent case. Settings and data analysis are handled by optional Windows-based PC software via serial, USB or Bluetooth connection.
