*This evaluation determined the sensor's responses to the liquids shown above. 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.



Ken Wilcox Associates (KWA) has previously evaluated these sensors on one or more Franklin Fueling Systems ATG consoles. Results from the alarm functionality testing with the EVO600 and EVO6000 consoles have been combined with previously evaluated sensor threshold data performed by KWA, as well as Carnegie Mellon Research Institute.
Sensors are reusable.
