The SG-2R probe for gamma measurement is designed to be used with any CSP survey meter. Its very good sensitivity makes it ideal to detect gamma emitters starting from very low background levels.

The SG-2R unit is part of the CANBERRA™ SMART Probe (CSP) family. It includes all key components of hardware circuitry (high voltage power supply, amplifier, discriminator, etc.). Also, the intelligence associated with controlling those components is located in the probe - that is control and storage of key parameters, settings, calibrations, probe ID, alarm settings (10 values for each unit to display with default setting), etc. Thus the probe is a fully integrated subsystem talking and transmitting the measurement to the instrument, which is used for display.
