RadEye SX Survey Meter
Compact multi-purpose survey meter for external scintillation probes, measuring count rate, surface contamination and dose rate.
The RadEye SX handles general count rate and surface contamination measurements as well as dose rate. The display and alarm LED remain visible while the instrument is worn in its transparent case, and all settings and data analysis can be done with optional Windows-based PC software.
The probes we most often supply with the RadEye SX are the BP19RD for beta and the DP6RB+ for alpha/beta.
- Operates with dual phosphor α/β, NaI(Tl) and plastic probes
- Up to 16 different probe configurations selectable in a submenu
- Probes are easy to replace in the field with a simple button push
- Weighs only 160 g with rubber protection
