Ordering Information
The new i-RAD offers an easily solution for incorporating radiation monitoring
in an exisitng or planned PLC managed monitoring system. Te 4 - 20mA
industry standard output provides simply connectivity for gamma dose-rate or 
count-rate monitoring over 50keV to 1.3MeV. i-RAD interfaces with a selection
from the range of Rotem R-200 Probes achieving a wide measurement range.
The logarithmic 4 - 20mA output can be user programmed to suit the application.
The i-RAD is wall-mounted with AC mains adapter (12VDC) powered and
features a large, multi-segment, backlit LCD display.
