For sites that screen hundreds of people a day — mines, large factories, logistics hubs — handheld testers create bottlenecks. Wall-mounted, non-contact screening stations solve this by reading a passive breath sample as a worker speaks or blows toward the unit, with no mouthpiece to change.
Mounted at a turnstile or gate, the station gives an instant pass/alert indication and can be wired into access control so a flagged result holds the door. Throughput climbs, consumable costs fall to near zero, and the screening is consistent regardless of who is on shift.
These stations are screening tools, not evidential devices — a flagged worker should be confirmed on a fuel cell analyzer before any action. Used that way, a wall-mount station is the fastest, lowest-friction way to keep an impaired person off the floor.
