*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.

**This sensor is identified as an interstitial sensor, but will function properly in other containment areas such as containment sumps, contained risers and other contained enclosures.  This sensor must be installed at the lowest point of the containment enclosure to insure early detection of liquids.  Results stated for used oil applicable to this sensor only.

*** Micro Sensor 794380-340 is not supported by TLS 450 series console.

****See Glossary

 

Comments:
Sensors are reusable.
208 and 209 sensors are also compatible with 300 series.
Comparison of TLS-450 with TLS-350 series console showed comparable results when evaluated with representative sensors.
