DKG-21M

Description

Direct reading personal dosimeter for personnel exposure monitoring.

EcotestCARD can be used either independently with PDC Ecomonitor software or within the automated system of personal dosimetry control ASIDC-21.

The dosimeter allows storing dose accumulation history with real time reference in the non-volatile memory, and communicating it to the computer. If the programmed threshold levels of gamma dose or its rate are exceeded, light and audio alarms are actuated.

• Сonforms to the CE standards
• Meets the requirements of IEC 61526 standard
• IP54

Purpose of Use

• Measurement of gamma and X-ray radiation individual dose equivalent rate (DER).
• Measurement of gamma and X-ray radiation individual dose equivalent (DE).
• Clock, alarm clock.

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.
