1.1 RDS-31 S/R Multi-Purpose Survey Meter
The new RDS-31S/R Multi-purpose Survey Meter continues the
line of the Mirion survey meters offering modern design and
approach to a wide range of radiation monitoring applications.
RDS-31 is a small hand held, battery-operated survey
instrument utilizing an energy-compensated GM-tube as a
primary detector. It is suited for a wide range of applications in
civil defense, firefighting, rescue, industrial and laboratory use
due to its versatile functions and rugged construction. With the
accompanying Configuration Software, it is easy to optimize the
behavior of the instrument to meet the various working
conditions and needs. The menu functions, which are available
to the end user, can be selected from the bare essentials (back
light activation only) to functions allowing the alarm limit
setting, dose resetting and histogram functions configurations.
In other words, this meter has its place wherever the user
wishes to observe the ionizing radiation in his/her environment
or work surroundings.
RDS-31 features excellent ergonomics; it is lightweight and
easy to handle with visual and audible alarms and a built-in
vibrating alarm. The instrument can be held and handled firmly
even under difficult conditions thanks to the rubber grip around
the instrument. The large graphical display with an Energy Save
Backlight can be easily read both in total darkness and in direct
sunlight. Additionally, to increase the easy operation of the
instrument, Shortcut-operations can be configured to the
buttons. This function allows the easy and configurable method
of performing repeated operations such as the Manual Histogram
Sample collection, the Dose value display, the Diagnostics etc.
In addition, to help the users to become accustomed to the
Shortcut-function, a novel Visualization display function can be
configured into the operations. With this aid, it is possible to
adjust the button press to the desired length.
