Nightshift Atmosphere Sniffer

Nightshift Atmosphere Sniffer is a palm-sized sampler that draws air across replaceable chemical wafers and identifies leaks, combustion products, narcotics, and the first sour hints of failing scrubbers. Operators learn to sample low corners and warm vents rather than wave it heroically in the middle of a room. Used wafers retain contamination evidence; tossing them casually can expose a crew's route or poison the next person sorting reclamation. Dim controls, tactile indexing, and a warm battery grip suit workers who live under emergency lighting. Day crews often over-brighten the panel, shortening emitter life and leaving the next watch with a petty maintenance feud.
