Rados RDS-31
Multi-Purpose Survey Meter
|
The new
RDS-31S/R Multi-purpose Survey Meter is part of the RDS
family of RADOS survey meters and offers modern design and an
advanced approach to radiation monitoring. The RDS-31 features
outstanding ergonomics; it is lightweight and easy to handle
with visual, audible and vibrating alarms.
The
large LCD screen includes an automatic illumination control
feature with an energy saving backlight that can be easily
read in total darkness and in direct sunlight. To make the
instrument even easier to use, the buttons can be configured
with easy to understand Shortcuts. The Shortcuts allow the
user a straightforward and simple way to configure the
instrument for performing repeated operations such as the
Manual Histogram, Sample Collection, Dose Value Display, and
Diagnostics. In addition, to help the users to become
accustomed to the Shortcut-function, a Visualization display
function can be employed. With this feature, it is possible to
adjust the length of button pressure time to a desired
setting.
With a
simple cable connection to existing RADOS probes, the
capabilities of the RDS-31 can be extended to include the
detection and measurement of other types of radiation. The
meter provides an additional protective function to the user:
while using external probes, the meter is simultaneously
measuring the dose rate with its internal detector. This is
all done in the background and an alarm is triggered in the
event of a dose rate or an accumulated dose exceeding the
alarm thresholds.
