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 applications in civil defense, industrial and laboratory use.

Fields of application :
- Industry
- Nuclear
- Emergency units
- Army

Features :
- H*(10) ambient dose equivalent dose and dose rate
- wide range of external alpha, beta and gamma probes for direct connection with RDS-31
- new ergonomic design
- large graphic screen, confi gurable backlight with automatic illumination control
- high impact durable case construction , IP-67 immersion proof
- internal memory to store measurements
- flexible histogram functions
- firmware of instrument upgradable through cable link
- configurable shortcut functions

Radiological Characteristics :
- radiation detected: gamma and X-rays, 48keV...3MeV. Alpha, Beta radiation with an external probe
- detectors: one energy-compensated GM tube, energy response according to ambient dose equivalent H*(10)
- dose rate measurement range: 0.01 µSv/h...0.1 Sv/h or 1 µrem/h...10 rem/h
- dose measurement range: 0.01 µSv...10 Sv or 1 µrem...1000 rem
- resolution: three signifi cant digits or 0.01 µSv/h on dose rate and 0.01 µSv on dose ( 1 µrem/h on dose rate and 1 µrem on dose)
- calibration accuracy: ± 5%, 137Cs , calibration direction and in the calibration fi eld, temperature +20 °C (68°F)
- dose rate linearity: ± 15% ± least signifi cant number 0.05 µSv/h...0.1 Sv/h (5 µrem/h to 10rem/h)
- variation of the response due to photon radiation

Electrical Characteristics :
- power supply: 2 AA size batteries (alkaline or NiMH)
- contacts for external power and charging of NiMH battery (charging conditions +5... +35°C)
