RADOS RDS110 Portable Radiation Survey Meter

RADOS RDS110 Portable Radiation Survey is a sophisticated instrument which enables reliable and stable measurement of low background dose rate registering even the smallest meaningful changes in dose rate values. The automatic self diagnostic system ensures the continuous correct functioning and calibration of the unit.

Description :

Rados RDS 110 multi purpose survey meter is a versatile radiation detection meter which has been designed for a wide range of applications in different fields of rescue and other operations involving a possibility for abnormal radiation levels. The functions comprise dose and dose rate measurements and registration with extended upper limit ( 100 mSv/ h) . Both the dose rate and dose alarm levels can be selected from a menu.
