Specificity Results (in addition to above):
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.

Comments:
The consoles in each series are identical other than there name for marketing purposes.  Each of the consoles within a given series will perform identically. 
The 8601 Series consists of the following derivatives: TLS4, TLS4B, TLS4c, TLS4i, and TLS-S1 consoles.
The 8600 Series consists of the following derivatives: TLS-450PLUS and TLS-450 consoles.
The TLS-3xx Series consists of the following derivatives: TLS-350, TLS-350Plus, TLS-350J, TLS-350R, TLS-300, TLS-300C, TLS-300i and Red Jacket ProMax and ProPlus consoles.
These sensors can easily be removed, cleaned, and reinstalled if an alarm is triggered or for periodic testing.
This listing is for redesigned sensor model 794390-409.  The cable length remains the same (284”) as the original sensor.  The original design of the sensor has mesh netting around the sensor.  The new design does not have mesh netting around the sensor.  The original design 409 sensor remains listed under Veeder Root ILS-250, 350, TLS-250i, 250i Plus, 300, 300C, 300i, 300PC, TLS-350 Series, TLS-450 Series, Red Jacket ProMax and ProPlus with Interstitial Liquid Sensor for Fiberglass Tanks 794390-401, 404, 407, 409, Interstitial Liquid Sensor for Steel Tanks 794390-420, 460, Liquid Sensor for Sumps 794390-206 interstitial Detector (Liquid Phase).
