The NMT I-131 Air Monitoring Kit provides both breathing zone and stack monitoring with 2 open face sampler heads. An in-line combination filter handles stack discharge, while an open face combination filter holder filtrates the breathing zone. 

Each system comes complete with 20’ of tygon tubing, 2 calibrated openings, 2 combination filter holders, 1 box of a hundred (activated charcoal filter paper) and a vacuum pump.
