Software accessory for the PRM-8000 includes our GeigerGraph software for a Windows
PC, along with a
specialized USB data cable. Just
set the PRM's data port for Pulse Output, and then each pulse or count from the PRM is transmitted through the
data cable, and via the software, then displays and graphs those counts per minute in
terms of the Current reading, an Average, and Minimum and Maximum counts per minute
(CPM) over the test period.
The GeigerGraph software is especially useful for monitoring environmental
radiation, alerting you to any elevated levels relative to your typical
background count. The software issues an audible and
visual alert whenever the CPM exceed a user set desired level. For
example, the picture below shows the program first monitoring background
radiation, but then halfway through the test period, issuing a visual alert
because some radioactive "event" caused the radiation counts to exceed the user
set Alert Level of 100 CPM.
As a full Windows program, GeigerGraph can optionally run in the
background while you multi-task, notifying you only when your pre-determined
Alert Level is exceeded by actual radiation counts.
configure the program so that a Radiation Alert executes a computer program or batch
file, and/or sets voltage to another serial port on the computer to trigger a
relay switch that stops a machine, for instance.
Pleasing interface, including
and easy to understand running total and summary of Radiation Count
data, attractive 3D graphing, a flashing LED with each radiation count,
and handy speed buttons.
Identify your monitoring station and associated data records,
including graphs and spreadsheets, by the Person Monitoring, Location,
Altitude, Geiger Counter Model, etc.
The count data for each minute is recorded on an
Internal Spreadsheet, and
you can make notes for each of those minutes for analysis that you may be
The program also saves the radiation count data every minute to
a text file that can be exported to an external spreadsheet program such as Excel or Lotus
123 for further analysis.
GeigerGraph also incorporates a simulation designed to mimic the
recording and graphing of radiation counts in the instance where you have no
compatible digital Geiger counter plugged into your computer to produce "real"
pulses. The simulation demonstrates the graphing of background
radiation, followed by an alertable and elevated radiation count from a
theoretical radioactive "event".
The data cable has a 3.5mm stereo plug on one end which plugs
into the Geiger Counter's dual miniature jack. The output at the tip of the
plug provides a positive 5 volt pulse each time the Geiger counter detects a
The opposite end of the data cable is a standard USB
This specialized USB Data Cable comes in a generous
6 foot length.
Software comes on a CD-ROM
which the user installs on the computer's hard drive, so the CD can be removed
after installation for running of the program.
Software is a Windows program which can run on any PC with
Windows 98 or later.

This program, which gives one access to the wildly popular
Radiation Network, is a more powerful version of GeigerGraph, with all
of the features of the standard version, but with the additional capability to
share Radiation data in real time over the Internet or a
LAN, and to monitor that data through a Radiation Map and a series of
