Overview
The SABG-100 probe for measurement of surface contamination is designed to be used with any CSP survey meter or any other device able to handle CSP protocol. Its phoswich detector with 100 cm² detection area makes it an ideal tool for direct measurement of alpha, beta and gamma emitters. The probe is part of the Canberra SMART Probe (CSP) family and includes all key components of hardware circuitry with intelligence located in the probe for controlling components, storing parameters, settings, calibrations, and alarm settings. Features include calibration via PC, easy removable grid for decontamination, ergonomic counting mode selector on probe body, and new probe angle for hands-free contamination measurement. The probe can store up to 1000 data points and supports multiple measurement units (CPM, DPM, DPM/100 cm², c/s, Bq, Bq/cm²). It connects via 1.5 meter or 20 meter CSP cable and can be upgraded via CSPS software.
