Area Monitors MAR-781 & MAR-782 Hitachi


This instrument is the area monitor that measures the gamma dose rate in the working environment. Equipped with large LED display and loud buzzer alarm function, it is easy to see and hear the measurements from people nearby. Moreover, it is small and light weight enough to easily carry around.

Features:


  • For facilities using Gamma
  • Two models, high-sensitivity and wide-range
  • Available to suit specific target dose rate
  • For facilities using Gamma
  • Two models, high-sensitivity and wide-range, available to suit specific target dose rate
  • Large display
  • Equipped with alarm and external signal output
  • Belt and wall-mounting fixtures provided
