RadAlert200-Rendering.jpg

The Rad Alert 200 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 separate panels to display exposure rate (mR/hr), total integrated exposure (mR) and total exposure time on a remote alarm that is tethered to the primary alarm. The primary alarm includes a digital timer that counts time when radiation is present and a room door is open. This feature can be useful for routing patient safety QA or as a stopwatch in the event of an emergency. 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. A separate dose trigger is also included that can be set by the user. When the dose exceeds this level a separate yellow light turns on.

Includes a 30 meter cable for easy connection between monitor and remote alarm.
