PRODUCT  DESCRIPTION

The DRM-2D is a highly sensitive Monitor, based on a CsI(Tl) Scintillator, (30x30mm) crystal optically coupled to PMT with 0.5 mm aluminum  housing and solid Mu Metal shield, designed to be continuously used in areas where exposure levels are required to be monitored. 
The instrument is powered by an external AC source with NiMH backup batteries for backup. Two flashing LED’s on the cover of the monitor show the radiation and communication statuses, while another two LED’s display the power origin (AC Power or Batteries).
