TRACER GAS TESTING
Available from Lagus Applied Technology Inc
The underlying concept of tracer gas testing is that a gaseous taggant (tracer) can be dispersed in such a way that by following the movement of, and measuring the concentration of, tracer gas one can determine airflow and contaminant movement in complex situations
The movement of a contaminant can be investigated using a localized tracer injection and sampling for the presence of tracer at various locations. Tracer gas techniques can accurately measure the flowrate of air or other gas in a duct, stack, or pipe when conventional flow measurement techniques are inappropriate.
