The BGS model 205 decrepitometer
Because the model 105 decrepitometer requires an old
PC computer with an ISA card slot (now superseded), the
decrepitometer instrument has been redesigned and the software
re-written to operate on a standard single-board Linux computer.
This system uses the same furnace, sample tube assembly and power
control unit as the model 105 instrument.
It operates in the same manner as the previous model 105. But the software has
been updated to be more convenient and has a fully graphical
interface. The temperature and counts are monitored and shown on
screen during the analysis, and simultaneously plotted on screen.
The data is saved to a file upon completion, and the graphical
plot can also be printed if required and easily regenerated from
the saved data file.
The decrepitometer has been rebuilt to operate on a
stand-alone Linux (ARM) single-card computer. The computer
connects to a standard computer monitor, keyboard and mouse and
includes network connection. The computer and interface is in a
compact 10 * 12 * 5 cm enclosure.

The furnace and control unit is the same as used in the model 105 decrepitometer.
