*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.
**The "high" and "low" refer to high and low level alarm points of float switch
sensors.

See glossary.
Specificity Results (in addition to above):
Activated:
synthetic gasoline, jet-A fuel, n-hexane, toluene,
xylene(s)
Not activated:
water (polymer strip only)
Comments:
Polymer strip must be air dried
after exposure to unleaded fuel.
Polymer strips must be cleaned with solvent
and dried after exposure to diesel.
Comparison of TLS-450 with TLS-350 series console showed comparable results when
evaluated with representative sensors.
