Simulated Contamination Instruments

Fully functioning simulated versions of industry handheld contamination probes and detectors.





  • Simulates features and functions of the Mirion GMP-25 External Pancake Probe when connected to SIM-Teq RDS-31TD
  • Realistic response based on source/detector geometry
  • Detects simulated α, β, or α+β Contamination Sources
  • Demonstrates saturation when detector response is > 50,000 cps
  • Use with any SIM-Teq RFID contamination source(s) OR respond to TWR source or control manually with SCC application
  • Built with real GMP-25 hardware 1


  • Power - One (1) Internal rechargeable 2000mAh 3.7V Lithium-ion Polymer battery
  • Battery Life - >8 Hours
  • Environmental – Drop and Water Resistant
  • Wireless Communication - ISO/IEC 15.693, 13.56 MHz, ≤1.4 W
  • Dimensions - 37.5 x 70 (14.8 x 2.75 in.)

Additional Features

  • Probe connects directly to any RDS-31TD training meter using a standard probe cable (auto-response of internal simulated GM detector retained)

  • Operates independently with any SIM-Teq Contamination Sources, OR manually controlled by an instructor

  • Range of operation is up to 4 inches (100 mm) from a surface location of Contamination Source

  • Response performance characterized from real instrument

  • USB-C charging port

  • LED Battery level and charge indication
