Alpha Probe

The SA-100 probe for measurement of surface contamination is designed to be used with any CSP™ survey meter.

Tag Features

  • Alpha surface contamination measurement
  • 100 cm2 ZnS(Ag) scintillation detector
  • Belongs to CSP family
  • Calibration via PC
  • Easy removable grid for decontamination


Calibration and QA measurements can be performed directly with the probe, without 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. It can also be connected via CSP-COM™ modules to integrate a third-party system and behave as a contamination sensor sub-assembly.

Once calibrated, the SA-100 unit is ready to be used as a plug and play probe to start a QA measurement in CPM, DPM, DPM/100 cm2 with US units survey meters; or c/s, Bq, Bq/ cm2 with SI units survey meters.

A SA-100 probe includes a protection grid that is very easy to remove for decontamination purpose. Even with the grid detached, the probe remains operational and the whole assembly stays light tight. The entrance window is attached on a removable metallic frame that is fixed on the probe body with flat screws and is quickly changed, reducing the service time.

The SA-100 probe can be upgraded (probe’s firmware) via CSPS platform, a USB cable and a PC.
