Digital Pocket Dosimeter ECOTEST Card DKG-21 (EPD)

Delivery Kit

• MKS-05 TERRA dosimeter-radiometer
• operating manual
• leather case
• packing box

Purpose of Use

• Measurement of individual dose equivalent (DE) of gamma and X-ray radiation

• Measurement of individual dose equivalent rate (DER) of gamma and X-ray radiation

Features

Storage of dose accumulation history in the non-volatile 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

Gamma and X-ray radiation DER and DE threshold levels programming 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 GeigerMuller counter

Ingress protection rating IP31

Clock, alarm clock

Software allows to:

– program parameters and operating modes

– read dosimetric measurement results

– review and print dosimetric information as reports

– save and export read information as a report or text file for further processing by other text editors

– import previously stored dosimetric information for processing and analysis
