beta radiation detector
The compact SB-20 probe for measurement of contamination is designed to be used with any CSP survey meter. Its 20 cm2 plastic scintillation detector reduces the background noise, and makes it an ideal detection tool for small areas.
SB-20 is part of CANBERRA's new 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 taking and transmitting the measurement to the instrument, which is used for display.
