Digital Display Geiger Counter Kit

This sensitive geiger counter kit uses a Russian geiger mueller tube and a microcontroller IC to measure and display radiation counts on a 3 digit display. The counter is sensitive to beta and gamma rays and will indicate the presence of radiation with a click from the built in speaker and a brilliant blue-green flash from an LED. In addition the microcontroller IC outputs the count to a pale yellow 3 digit display (the display is visible indoors but not bright enough to viewed outdoors in order to conserve battery life). The unique feature of the microcontroller digital output is that you can select either counts per minute or total counts to be displayed.

The unique feature of the microcontroller digital output is that you can select either count per minutes or total counts to be displayed. The total count display uses a unique set up with multiplier Leds to indicate 10, 100, 1000 times counts allowing the counter to display 999,000 before an overflow LED lights up.
