  • Standard surface contamination measurements, in cps
  • Contamination measurements with histogram function
  • Visual and audible alarms
  • Small and handy
  • Software RDS-CSW for parameter setting, histogram reading and nuclide calibration (optional)

The RDS-80 Contamination Monitor is an easy to use contamination instrument based on pancake GM-tube. Measure alpha, beta and gamma as cps or Bq/cm².

The functions comprise contamination measurements with alarm functions and automatic conversion to activity value and additionally surface contamination measurement with a possibility to store the histogram events into the meter´s internal memory (external accessories required for downloading the data into a PC via IrDA port).
