Specificity Results (in addition to above):
Activated: synthetic gasoline, n-hexane, jet-A fuel, toluene, xylene(s).
LS and PD series responds to any liquid with an index of refraction different than air.
PD series responds to any conducting liquid.

Comments:
Detectors are listed as interstitial due to intended use.
Sensors are reusable.
