Specificity Results (in addition to above):
Activated:  synthetic gasoline, n-hexane, jet-A fuel, toluene, xylene(s).

Comments:
Evaluator claims sensors will respond to any liquid once threshold has been exceeded.
After exposure to diesel, RE400-204-5 Dispenser Pan Monitor reading may not return to pre-contaminated level.
Sensors are reusable.
