*Evaluations determined these sensors' responses to the liquids shown above and those indicated in the following section. Biodiesel blends B6-B20 meeting ASTM D7467 and biodiesel B100 meeting ASTM D6751 would also produce an alarm if the sensor threshold is exceeded. Responses to these fuels were not determined, but would be expected to be very similar to the diesel responses.
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.
