RDS-31iTxSD is a small handheld, battery operated survey instrument using a silicon diode as primary detector. RDS-31iTx SD features nice 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-11-3/15-3/12-3/12L-3/12H-3 can be connected to RDS-31iTxSD directly through Binder connector. User protection while using external probe by measuring simultanously instrument dose rate.
