Biodiesel blends 136-820 meeting <br />ASTM D7467 and biodiesel 8100 meeting ASTM D6751 would also produce an alarm if the sensor threshold is <br />exceeded. Responses to these fuels were not determined, but would be expected to be very similar to the diesel <br />responses. <br />***This sensor is identified as an interstitial sensor, but will function properly in other containment areas such as <br />containment sumps, contained risers and other contained enclosures. This sensor must be installed at the lowest point <br />of the containment enclosure to insure early detection of liquids. <br />Specificity Results: <br />Evaluator claims both 794380-343 and 794380-344sensors will respond in any liquid after the sensor threshold is <br />http://www.waterboards.ca.gov/ust/leakTrevention/lgl 13/vendors/veeder root u.shiml 9/9/2013 <br />
