Gamma Alarm Model-L

Gamma Alarm Model-L

The INC Model-L is a radiation area monitor designed to alert personnel to radiation exceeding selected levels. This alarm system provides an indication of radiation levels at areas such as transportation docks, storage sites, nuclear medicine facilities, laboratories, industrial centers, and radiography installations.

When the radiation intensity exceeds a pre-set level the green light goes out, an audible alarm will sound and the red light will be activated. The alarm is pre-set to trip at 2 mR/hr (user adjustable).

The sensitivity adjustment is the control mounted on the printed circuit board (screwdriver adjust). Turning this control CW increases the sensitivity. DISCONNECT POWER BEFORE REMOVING COVER OR ADJUSTMENT.
