GCK-01 Series of Analog Geiger Counter Kits
Are used for detecting radioactivity and performing nuclear experiments. The GCK-01 model has numerous customizable options and comes as a ready to build kit or may be purchased assembled and tested. This series of Geiger Counters have Digital Pulse Output Port, External Power Supply Port and Headphone Jack. Primary indicators are an audio click and an LED blink each time a radioactive particle is detected.
The GMT-01, detects alpha, beta, and gamma radiation.
The GMT-02 & GMT-06 detect beta and gamma radiation.
Refer to our Geiger Counter Tubes page for more information on these Geiger Mueller Tubes.
| The GMT-01 and GMT-02 are available as an external wands. | Enclosure cases for GCK-01 series. |

The GCK-01 series features:
- Digital Output Port - Provides a TTL logic pulse each time a radioactive particle is detected. Used to connect various digital adapters, like our DMAD Digital Meter Adapter, which turns our analog into an accurate digital Geiger counter.
- External Power Jack - 2.5mm power jack for external power.
- Headphone Jack
While the Geiger counter is on (powered), the bare 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 or case is recommended and available for separate purchase based on the option chosen for your kit.
Case size: 3.5" x 5.75" x 1.25"

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.
Digital Meter Adapter -- Turns our analog into a accurate digital geiger counter
External Power Jack -- 2.5MM power jack for external power.
While the geiger counter is on (powered), the PC board contains exposed high voltage components. Even when the ciruit is turned off (power is removed) the capacitors still may hold a high voltage charge. A project box or enclosure is recommended.

Digital Meter Adapter for Analog Geiger Counters
The Digital Meter Adapter is a expansion module for analog Geiger counters that adds many features to your analog Geiger counter. The DMAD reads positive +5V pulses from an analog Geiger counter. It counts each pulse that represents a radioactive particle detection. The pulse counter has two selectable time periods; a one second time period for Counts Per Second (CPS) and a sixty second time period for Counts Per Minute (CPM). Another function is Random Number Generator. This allows each radioactive particle detected to generate a true random number. The last feature is a serial output that when used in conjunction with an optional TTL/USB Cable output the count data to a Windows Program. The DMAD has the three most popular functionalities in one module to enhance the capabilities of analog Geiger Counters.
Countable Pulse Resolution & Range 1 Count Per Minute (CPM) - 9,360 Counts Per Second (CPS)
Radiation Resolution & Range 1.0 uR/hr - 655 mR/hr
(Metric) .01 uSv/hr - 6.5 mSv/hr
LCD Display 16 character by 2 line LCD (liquid crystal display) with back light provides easy to read output.
