Go Keychain Breathalyzer
About the original
The BACtrack Go Keychain Breathalyzer is a compact personal BAC tester with a fold-out mouthpiece, a blue LCD readout, and an internal solenoid breath pump that filters ambient air for accuracy. BACtrack, founded in San Francisco in 2001, makes both fuel-cell and semiconductor breathalyzers for consumer and professional use. The Go sits at the entry-level tier and uses BACtrack's MicroCheck semiconductor sensor, put through a patented burn-in process that the company says yields more consistent readings than standard semiconductor units. It measures 1.45 by 0.55 by 2.44 inches and weighs 2 ounces with batteries. The Supreme SS2018 version adds box logo branding to the housing.
About BACtrack
BACtrack is an American breathalyzer manufacturer founded in 2001 by Keith Nothacker in San Francisco, California, operating as a division of KHN Solutions. The company worked with the U.S. Food and Drug Administration to establish the evaluation criteria for personal breathalyzers and received the first FDA marketing clearance for a consumer unit in 2004. BACtrack pioneered fuel-cell sensor technology in pocket-sized devices and launched the first Bluetooth-connected smartphone breathalyzer in 2013. The Go is a keychain-format unit with a folding mouthpiece, semiconductor sensor, and a battery rated for 150 tests. Supreme collaborated with BACtrack on the SS18 BACtrack Go Keychain, a working breathalyzer in white with red box-logo branding.
