Comments:

Evaluations determined these sensors' 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.

Specificity Results (in addition to above):

Sensor will alarm if it is raised from the bottom of the containment. Sensor can easily be removed, cleaned and reinstalled if an alarm is triggered or for periodic testing.
The consoles within each series are identical other than their name for marketing purposes. Therefore, each of the consoles within a given series will perform identically. The TLS-4 Series consists of the TLS-4 and TLS-4B. The TLS-300 Series consists of the TLS-300, 300C, 300i, 300PC, and Red Jacket ProPlus consoles. The TLS-350 Series consists of the TLS-350, 350R, and Red Jacket ProMax. The TLS-450 Series consists of the TLS-450.
