DMAD Expansion Module for Geiger Counters

DMAD Expansion Module for Geiger Counters

The New Digital Meter Adapter is now a universal expansion module. It is a combination of the original Digital Meter Adapter, RS 232 interface adapter for PC & Random Number Generator Adapter. The new DMAD has all three functionalities in one module to enhance the capabilities of Geiger Counters.

DMAD Functionality

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

Shown with optional stand (not included)

Random Number Generator Functionality
This adapter plugs into the digital out of the analog geiger counters and provides a random number each time a radioactive particle is detected. The geiger counter is set up to read background radiation. The random numbers generated are truly random since they are based naturally occurring radioactivity.
The random number generate may be set to the following ranges:

1-2 (Binary/Heads or Tails) 1-4 1-8 1-16 1-32 1-64 1-128

The random number generator is compatible with analog meter geiger counters that use either an internal tube or a wand with shielded cable.

Typically, depending upon location, the generator will generate 20-40 random numbers per minute. TTL Serial Output Random numbers are sent out via a TTL serial port that may be interfaced to a micro controller or PC.

RS-232 Functionality
This Digital Adapter also provides an RS-232 computer output for use with Images Company Geiger Counter Graphing program.
