LDM 250
Active Dosimetry - Readers
LDM 250
USB Desktop Dosimeter Reader
The LDM 250 reader operates using software packages
installed on computer (PC) and communicates with the
DMC 2000S, GN, X and XB dosimeters in pass-by data
exchange mode.
Associated to the DOSICARE or DOSIFAST software,
the LDM 250 reader is used as an interface to activate a
dosimeter (to switch in counting mode) or to deactivate
it (to switch in pause mode).
Associated to the DOSIMASS software, the LDM 250 is
used as an interface to read and write the internal data
of the dosimeter.
Driven by LDMNet software, the LDM 250 is able to
lock the dosimeter in the sleeve during all the transac-
tion, check the frequency emitted by the dosimeter in
alarm, switch on the dosimeter then release it, at the
end of the transaction.
