PERSONAL DOSIMETER DKG-21M MALAYSIA

Features

Stand-alone use or use within automated system of personal dosimetry control.
Storage of dose accumulation history in the nonvolatile memory with real time reference.
Transfer of dose accumulation history through the infrared port to the computer.
Blocking the mode of power supply switch off until the data reading procedure finished.
DER and DE threshold levels programming of gamma and X-ray radiation with the help of the computer or manually with control keys.
Blocking certain indication modes in response to the computer command.
Light and audio alarms when programmed threshold levels exceeded on DER and DE of gamma and X-ray radiation.
Display automatic switch off if current gamma background is lower than the preset threshold level with instant switching on at:
pressing any control key;
gamma background increase above the preset threshold level;
alarm clock ringing.
Periodic self-testing of batteries and detector.
Energy-compensated Geiger-Muller counter.
