RadAlert100-Rendering.jpg

The Rad Alert 100 is the next generation area monitor that includes a built in GM Gamma detector for monitoring rooms where radio nuclides may be present or where devices producing radiation may be located. This unit includes a devoted panel to display total exposure time on a remote alarm that is tethered to the primary alarm. The primary alarm contains a digital threshold panel that indicates the level at which the alarm will trigger. The monitor has a backup powered by either rechargeable NiMH or alkaline AA batteries. The rechargeable batteries are maintained on a trickle charge. The detector unit has an adjustable trigger level with the level displayed on a digital display. The slave unit contains an audible buzzer with an adjustable volume control that can be turned on or off with a switch mounted on the side of the unit. Includes a 30 meter cable for easy connection between monitor and remote alarm.

This unit can be upgraded to the RadAlert 200 for additional functionality.
