Manufacturer's specifications
Type 1 sensor is recommended by manufacturer for detecting liquid and vapor gasoline, alcohol-blend fuels, and JP-4 jet fuel in wet or dry monitor wells.
Type 2 sensor is recommended by manufacturer for detecting fuel oils #1 and #2, A2M, JP-4 jet fuel, JP-5 jet fuel, unleaded gasoline, and alcohol blend fuels in wet monitoring wells only.
Comments
The detector is not reusable and must be replaced after contact with hydrocarbons. California regulations require sensors to be tested annually to verify proper operation. This sensor is a self-destruct type and therefore cannot be used in California.
