 Our selection of
Geiger Counters, namely the Inspector, the Inspector EXP, the Radalert/Digilert
100,
the Monitor 4, and the PRM-8000 come with an optional
Software accessory, including a
data cable to interface to a computer or data logger, along
with our GeigerGraph software for a Windows PC. Each pulse or count from the
Geiger Counter is transmitted through the
data cable, and via the software, 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.
Features:
 |
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.
|
|
You can
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
conducting.
|
|
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
count. |
| The opposite end of the data cable is a 9 pin RS-232
connector for an IBM PC compatible serial port (or in the case of the
PRM-8000, a USB connector). |
| 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. |

We also offer a free Demo version of the GeigerGraph
software. Click on this Demo link or select the
navigation button above to try it out, and then return here if you want to order
the full version of GeigerGraph.
Order the Standard Version of GeigerGraph below, or click here for
GeigerGraph for Networks, a more powerful version
which gives one access to the wildly popular
Radiation Network. This product typically ships within
1 business day.
And here is a Shopping Cart button for just the Data Cable with
Serial connector.
 And if you need a Serial to USB Adapter because your PC does not have
a Serial Port, as in the case of some modern PC's, especially laptops, then
order that below.
This comes with its own driver software on CD which should be installed
before using the Adapter.
