Specificity Results:
This evaluation determined the sensor's
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.
Manufacturer’s Specifications:
Manufacturer states that systems require no
calibration.
Annual functional test required.
Comments:
Sensors are reusable.
