LDM 320D & LDM 320W Hands-Free Dosimeter Readers

The LDM 320D and LDM 320W readers operate using software packages installed on computer (PC) and communicate with DMC 3000 dosimeter and DMC 2000 and SOR families in hands-free data exchange mode. When used with the DosiCare, DosiFFR, or compatible access control software, the LDM 320 reader is used as an interface to activate a dosimeter (to switch into counting mode) or to deactivate it (to switch into pause mode). When used with the DMC User software, it functions as an interface to read and write the internal data of the DMC 3000, SOR and DMC 2000 dosimeters.


The LDM 320D and LDM 320W are compact and low-cost dosimeter readers.
