DRM-1
The DRM’s detector features a linear response from 0.1µSv/h to 10Sv/h (10uR/h to 1000R/h).
The DRM-1 is a wall-mounted instrument that can be connected to the AC power with NiMH backup batteries. The radiation data is sent via 900 MHz FHSS or 2.4 GHz FHSS radios via the external antenna to a transceiver or via hardwire (RS-232 or RS-485) to a Remote Monitoring System. The DRM-1 can also be connected directly to a computer input.
Applications
• Perimeter or boundary surveillance
The DRM is a portable or fixed position device used for perimeter and/or boundary monitoring used to quickly identify changing radiological conditions.
• Collection of radiological survey data for real-time mapping and surveillance software
The DRM provides live radiological data for display, archiving and trending in real-time mapping software programs (e.g. TeleMap).

Technical Data
Technical Description
The DRM-1 is a wide-range GM tube-based Monitor 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).
