Technology
Why Fuel Cell matters.
Not all alcohol sensors are equal. The technology inside the device determines the reliability of every result.
AF-50AD · Fuel Cell
Electrochemical Fuel Cell
- ✓Detects only alcohol (ethanol) — zero false positives from acetone, perfume or food
- ✓Same technology used by law enforcement & professional workplace testing worldwide
- ✓Consistent accuracy across the full temperature range (-5°C to +50°C)
- ✓EN 15964 certified — accepted in regulatory audits and insurance investigations
- ✓Warm-up in under 5 seconds, ready for continuous fleet-scale testing

%BAC Accuracy
Standard devices
Semiconductor Sensor
- ✗Reacts to ketones, acetone & other substances — produces false positives in diabetic workers
- ✗Consumer/recreational grade — not accepted in professional compliance contexts
- ✗Accuracy degrades in extreme heat or cold — unreliable on outdoor industrial sites
- ✗Results not recognised by regulators or insurers — no audit value
- ✗No calibration standard — measurement drift over time cannot be detected
Device Components
Every part engineered for the field.
Mouthpiece Slot
Accepts single-use hygienic mouthpieces. Each employee uses a new, individually sealed mouthpiece — ensuring hygiene and preventing cross-contamination on shared devices.
OLED Display
High-contrast 128×64px OLED screen displays BAC value, test number, time and battery level. Readable in full sunlight and in low-light underground environments.
Bluetooth 5.0
Pairs instantly with the Sobber mobile app via Bluetooth 5.0. Results transmitted in real time to the cloud dashboard — no manual data entry, no risk of manipulation.
Status LED
Colour-coded indicator visible from a distance. Green for negative, red for positive, amber for calibration due. Supervisors confirm test status at a glance across a busy site entrance.
Power Button
Hold 2 seconds to power on. Device auto-warms in under 5 seconds. Auto-powers off after 3 minutes of inactivity — preserving the 1,500-test battery life across full operational days.
AA Battery Cover
Runs on standard 2× AA alkaline batteries — available worldwide, no charging infrastructure required. Critical advantage for remote mines and offshore sites with no reliable power supply.
Calibration & Service
Built for continuous operations.
The AF-50AD is designed for uninterrupted fleet deployment. Calibration every 12 months or 1,000 tests — whichever comes first. The device displays days remaining until next calibration on startup. When calibration is due, Sobber coordinates with your local service partner for minimal downtime.
