RDS-31iTx

Telemetry Survey Meter

The new RDS-31iTx is a Wireless Ready Telemetry

Survey Meter, utilizing the WRM2 communication

protocol for Wireless Remote Monitoring applica-

tions. The use of radiation telemetry equipment im-

proves the communication between workers, tech-

nicians and supervisors. It helps in making real time

decisions quickly, providing real time survey data. It

also reduces critical work time and most importantly

enhances safety and ALARA procedures.

FEATURES

• H*(10) ambient dose equivalent dose and dose rate mea-

surements

• wide range of external alpha, beta and gamma probes for

direct connection with RDS-31iTx

• new ergonomic design

• large graphic display, con gurable backlight with auto­matic illumination control

• high impact durable case construction , IP-67 immersion
proof

• internal memory to store measurement data

•  exible histogram functions

•  rmware of instrument upgradable through cable link

• operational parameters fully con gurable with CSW-31
software

• con gurable shortcut functions

• WRM communication 2.4 GHz 10 mW ISM radio for Euro­pean frequency range 900 MHz 100 mW ISM radio for US
frequency range

RDS-31iTx 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 applications in civil defense, industrial and labora-

tory use etc.

RDS-31iTx features excellent ergonomics; light

weight and easy handling, with visual and audible

alarms and internal vibrator. The large graphic dis-

play with Energy Save Backlight is well visible even

in sunny conditions due to the illumination control.

To extend the capabilities of the instrument, exter-

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

150 can be connected to RDS-31iTx

directly through

binder connector.

User protection while using external probe by mea-

suring simultanously instrument dose rate.
