RDS-31 S/R

Multi-purpose Survey Meter

The new RDS-31S/R Multi-purpose Survey Meter

continues the line of RADOS survey meters o ering

modern design and approach to radiation monito-

ring.

RDS-31 is a small handheld, battery operated survey

instrument using an energy compensated GM-tube

as primary detector. Due to its versatile functions

and durability it is suited for a wide range of applica-

tions in civil defense, industrial and laboratory use

etc.

RDS-31 features excellent ergonomics; light weight

and easy handling, with visual and audible alarms

and internal vibrator. The large graphic display with

Energy Save Backlight is well visible even in sunny

conditions due to the illumination control.

To extend the capabilities of the instrument, external

probes GMP-25/11-3/15-3/12-series and ABP-150

can be connected to RDS-31S/R directly through

binder connector.
