* ILS-250, TLS-250i, 250i Plus
** ILS-350, TLS-350 Series
*** Liquid Sensor for Sumps 794390-206 is no longer manufactured and is not supported by the TLS-450 series console.  It was replaced by sensor models 794380-208, 209 which are included on the NWGLDE list.

Specificity Results (in addition to above):
 Activated:  diesel, heating oil #2, water.

Comments:
Comparison of TLS-450 Series console with TLS-350 series console showed comparable results when evaluated with representative sensors in water and diesel fuel.
 Sensors are reusable.
