The Surface Activity Monitor quickly, conveniently and directly measures fixed and removable tritium activity on flat surfaces and can measure removable tritium on all surfaces

The instrument is portable, can have its calibration easily checked, produces no waste, and is much quicker and more convenient than scintillation testing for tritium on surfaces.


  • Measures removable tritium on smear paper.
  • Measures total tritium on flat conducting surfaces.
  • Simple and easy to use.
  • No waste.
  • Portable.
  • Optional calibrated source is available.
  • No P10 gas required.
