A highly sensitive, compact dosemeter to measure gamma and X-rays
This direct-reading dosimeter displays an accumulated dose as well as dose rate, and is suitable for measuring above 100 kVp of X-ray tube voltage.
Features
- Light and compact to fit in a pocket
- Alarm function equipped
- Wide measurement range from 1µSv to 10 Sv
- Accumulated dose and dose rate measuring
- Data holding function
- Easy to see display with backlight
