Fully functioning, assembled and tested visual Geiger Counter display uses the exact same components as our C7011 - Radiation Illuminator Display, but is sold without the shadowbox and power adapter.
Can be displayed as is or use your own custom frame or shadowbox.
The illuminator displays increasing levels of radiation in 5 steps on a large display that can be viewed from great distances. Normal background radiation levels are indicated by a bright red circle made up of 9 brilliant red LEDs (even in direct sunlight). As the ambient radiation level increases another band of brilliant yellow LEDs illuminate. Finally if radiation levels max out the illuminator (about 20 clicks per second), the illuminator lights up an outer orange-red band of LEDs, indicating that radiation levels may be dangerously high in your location.
The illuminator contains a built in speaker to produce the familiar clicks of a Geiger counter (can be disabled if desired).
