The Ghost Sniffer was said by Peter Venkman to be one of their little toys. However, this device samples the air for ghost activity as it is a form of detection equipment. In reality, it is a Bacharach model 300 sniffer combustible gas detecting device.


Ghostbusters (1984)

The Ghost Sniffer device was used twice during the Gozer incident of 1984, once with Ray Stantz in the ad "We're Ready to Believe You" and with Peter while checking out Dana's Apartment. When Dana asks if he was using the device correctly, Peter wasn't 100% certain that he was.

Ghostbusters: Afterlife

Egon Spengler left the Ghost Sniffer on a table near his wall of degrees in his Farmhouse's underground laboratory.

Secondary Canon History

IDW Comics

Peter used the Ghost Sniffer during a pro bono case that involved Alan Crendall and Slimer. A few months later, during summer, Peter used it during a week long investigation in Roswell. The next year, Ray used it in Bushwick on the Day of the Dead to take readings of concentrated, benign spectral activity for psychokinetic pattern research. During a dimensional overlap, Abby Yates used the Ghost Sniffer in conjunction with wearing a Long-Range P.K.E. Scanner to take readings in Lower Manhattan with Egon and discovered highly energized Ley Lines.
