TA - Model AIR-TBM Series -Basic Radiation Air Monitor
The AIR-TBM-SP uses standard 57-70 mm filters in T/A`s easy change, no leak filter, to trap any airborne radioactivity. The filter is under constant surveillance via pancake GM tube. Air is drawn through the system by a continuous duty pump. The unit is completely self-contained and portable. Room air is drawn in through the charcoal impregnated filter paper. Then through the pump and its 3 ft. exhaust hose that can be extended. The AIR-TBM air sample filter holder from the AC pump can be connected to the TBM-3SR-D through a unique ``groove and track`` bracket on bottom of TBM-3SR-D. This provides attachment of the air sampler filter holder for read-out with the TBM-3SR-D. The TBM-3SR-D is itself a compact surface monitor and survey meter.
