The SABG-15+ probe is designed for the measurement of surface contamination. Its good sensitivity makes it ideal to detect alpha, beta and gamma emitters for initial survey applications.

The SABG-15+ unit is part of the Canberra™ SMART Probe (CSP) family. As part of the CSP Family it is compatible with all CSP survey meters.

The SABG-15+ device 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 communicating the measurement to the instrument.

With high voltage and acquisition of the data occurring in the probe rather than the instrument, measurement quality is no longer dependent on external device quality (cable, host instrument). Moreover, a CSP probe is using a serial protocol to communicate with the host that can be an instrument or a PC.

Calibration and QA measurements can be performed directly with the probe, without even using an instrument, by connecting the probe to a computer with Canberra Smart Probe Software (CSPS™), allowing your instruments to remain deployed in the field.

Once calibrated, the SABG-15+ unit is ready to be used as a ‘plug and play’ probe to start a QA measurement in c/s, Bq, Bq/cm², CPM, DPM, DPM/100 cm² depending on the connected survey meter. The SABG-15+ probe connects to the CSP survey meter via a 1.5 meter or 20 meter CSP cable.

The SABG-15+ probe is able to store up to 1000 data points from a data logging procedure handled via the host instrument. These data are: index, date/time, measurement value, selected unit and counting time.

The SABG-15+ firmware can be upgraded via CSPS software, a CSP/USB cable and a PC.
