Geiger Counter Kit with Digital Display

Geiger Counter Kit with Digital Display Lowest new price: $270.00
List price: $270.00
Brand: LDB
Model: C6981

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. 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).C-6981

Features:

  • 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.
  • 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.
