SURFACE MONITOR/SEARCH TOOL

Model # TBM-6SP-ST

FEATURES:

* TWO SEPARATE DETECTORS:
  EXTERNAL - SCINTILLATOR 1" x 1" NaI(Tl) 
  INTERNAL - PANCAKE GEIGER

* LIGHTWEIGHT - FITS IN YOUR BRIEFCASE

DESCRIPTION: The TBM-6SP-ST features an internally 
mounted 2 inch pancake GM detector with window looking 
downward from bottom of case and an External Model 
PGS-3 1" x 1" scintillation probe for use as a Gamma 
Search Tool and $\mu $R Meter. A sliding shield protects 
pancake detector when not in use. This system is half 
the weight of other systems.
