RadEye G Series Gamma Survey Meters
Handheld gamma and X-ray survey meters for general radiation protection, available in several sensitivity and measuring range versions.
The G-10 is designed for quick and reliable general dose rate measurements, and the GF-10 for high dose rates. The GF-10’s intelligent ratemeter algorithm (ADF mode) detects even the smallest changes in dose rate immediately while suppressing random fluctuations, and all essential functions can be accessed while wearing protective gloves.
- Energy compensated GM tube for gamma and X-ray dose rate up to 3 MeV
- Linear over six decades, from background level to 100 mSv/h (G-10)
- High range model GF-10 measures up to 3 Sv/h
- Pocket size with large graphic display and bar graph
- Intrinsically safe Ex versions according to ATEX for explosive atmospheres
