Specificity
Results (in addition to above):
Activated:
synthetic gasoline, diesel, heating oil #2, water (AGW Sensor Cable
only).
Comments:
System
can monitor interstitial spaces.
Evaluations
also covered quantitative leak location.
AGW
Sensor Cable is reusable.
TFH
Hydrocarbon Sensor Cable is not reusable.
Lower
detection limit is calculated at MER only.
Cable is assumed to be equally or more sensitive at shorter lengths.
