STATE OF ART INSTRUMENTATION FROM AN INNOVATIVE COMPANY
digital contamination monitor [ Type : CM 711 ] Print
Technical Data

Digital contamination monitor Type CM711 designed, manufactured and supplied by Nucleonix Systems is a state of art micro-controller based unit which serves as a general purpose alarming radiation survey and contamination monitor for use in medical, industrial & other installations where radioactive isotopes are used for a variety of applications.
This unit is offered with an external probe housing a end window / pancake GM detector. It measures dose rate the range of
0 - 99.99mR/h in 4 linear ranges & countrate in the range of 0 - 99999 CPM in 4 linear ranges.
It has a lot of unique features which includes user interface through a set of four command buttons & the visual indication to the user is on a large analog LCD display . Data visualization is provided on both linear analog scale & direct digital display.
Features
  • Conforms to ANSI N42.17A performance specifications for Health Physics instrumentation (portable) & compliant.
  • Micro-controller based design.
  • Compact, Elegant and light weight.
  • Measures gamma dose rate in R/h or Sv/h
  • Measure beta contamination in CPM.
  • Dose rate accuracy of +/- 10% with Cs-137
  • Uses large area custom LCD display for dose rate visualization.
  • Preset alarm facility for generation of audio visual alarms.
