Bacharach Sniffer 300

Used in Ghostbusters to detect Ghost Vapor trails, the "Sniffer" was made by Bacharach/United Technologies. It is still available from a few sources but comes with a price tag of nearly $1,500 dollars. Sniffer 300 Series gas indicators are lightweight, portable instruments designed for intermittent measurements of combustible gas and oxygen deficiency. Rugged and rain resistant, these instruments represent a departure from traditional design. Each has a slender, high-impact thermoplastic case with a built-in handle and trigger switch. They each use easily-replaceable, field-proven sensors and internal sampling pumps for reliable service. The internal pump allows sampling up to 100 feet away. Designed for intrinsic safety, the Sniffer 300 Series instruments meet various approval agency requirements for use in Class I, Divisions 1 and 2, Groups A, B, C and D hazardous areas.
