965 Stack Continuous Air Radiation Monitor
The 965 Stack Monitor is a single-channel radiation monitoring system which operates over the range of 10 to 107 CPM. The system monitors gamma radiation and provides indication when the radiation level decreases below a fail threshold, exceeds a warn setpoint, exceeds a high set pointor exceeds an overrange setpoint.
The overrange feature provides two significant benefits. First, it prevents the system from displaying an on-scale but inaccurate reading should the detector become saturated. Second, it lessens the risk of damaging the detector by disabling it during an overrange condition.
