PAB-2 Smear Test Contamination Monitor

MiniTRACE CSDF is a unique multipurpose meter for contamination control, survey, dose rate and XRays radiation measurement.

The MiniTRACE CSDF is a multipurpose instrument fulfilling the functions of a contamination, survey and dose rate meter.

It is designed to improve the detection and the quantification of radiation contamination, making this a frontline tool in the protection against uncontrolled distribution of radioactive material

MiniTRACE CSDF provides several functions and measurement modes such as the dose rate, the activity or the count rate.

With the activity and surface contamination modes, different nuclides can be selected from the inbuilt library. The surface contamination mode is calibrated according to ISO 7503-1. Combined with the right accessories, wipe tests (surface contamination) and food tests (food contamination) can be performed. A mean value mode and a count up mode are provided to increase instrument accuracy.

Dedicated to surface contamination measurements

  • PAB-2 provides the best measurement for surface contamination in real-time with its dual proportional counter, sealed Ar-CO2


  • The PAB-2 is ergonomic with a large LCD screen display. It is also compatible with Printer and PC

Adaptable parameters

  • PAB-2 has adjustable contamination thresholds. Parameter access can also be restricted by a key for more security

Adapted to any situation

  • PAB-2 can be brought everywhere, and be used for measurements in a vehicle with its dedicated external power supply with car adapter

PAB-2 has a sealed Ar-CO2 detector, with a window diameter of 51 mm. It is sensitive to both alpha and beta radiation. Measuring time is then automatically adjusted according to this background value, taking into account the detection limit. PAB-2 has a guided aluminum plate for smear tests and filter measurements. Easy to clean in case of contamination 3,840 values can be stored on a flash memory, and then saved on another physical support for further data analysis.

  • Internal battery with charger – 8-hour autonomy
  • External power supply +14.4 VDC1A with car adapter
  • Drawer to accommodate a tray with dimensions ø 56 mm x 3 mm maximum (on request)
