Analog Geiger Counters are useful for detecting radioactivity and performing nuclear experiments. The GCK-01 model has numerous customizable options and comes as a ready to build kit. These Geiger Counters primary indicators are an audio click and an LED blink each time a radioactive particle is detected. Digital Output Port - Provides a TTL logic

pulse each time a radioactive particle is detected. Used to connect various digital adapters, like our Digital Meter Adapter, which turns our analog into an accurate digital Geiger counter. While the Geiger counter is on (powered), the PC board contains exposed high voltage components. Even when the circuit is turned off (power is removed) the capacitors still may hold a high voltage charge. A project box is recommended and available for separate purchase based on the option chosen for your kit. This Geiger counter outputs audible click and will blink a LED with each radioactive particle it detects. In addition it has two digital outputs that may be connected to a number of accessory instruments; a data logger, Digital Meter adaptor that outputs an approximate radiation level, RS-232 adaptor to plot radioactivity on a PC, and true random number generator. Using the analog meter adaptor, the geiger counter can approximate 3 radiation ranges: 0 to 1 mR/hr, 0-10 mR/hr and 0-100 mR/hr (or 55 mR/hr depending upon GM tube selected). This Geiger counter with a DMAD is compatible to our free Radiation graphing and monitoring software. Digital Output - Provides two buffered TTL logic pulse each time a radioactive particle is detected. Used to connected to various digital adapters: The Counts Per Second (CPS) has been measured in excess of 5000 CPS.
