Technology
No evidence without sound readings.
Evidence is only as good as the sensor that produced it. Here is why the AF-50AD uses a fuel cell.
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
±0.005
%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
Each part serves the evidence.
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 on outdoor industrial sites and in low-light underground environments.
Bluetooth 5.0
The result goes straight to the Sobber app via Bluetooth 5.0. No one copies it: no manual entry, no risk of manipulation.
Status LED
Colour-coded status indicator visible from a distance. Green for negative, red for positive, amber for calibration due. Supervisors can 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
Calibration you cannot forget.
A result only has value if the device is up to date. The AF-50AD is calibrated every 12 months or 1,000 tests, whichever comes first, and shows the days until the next calibration at each startup.
Calibration interval: 12 months or 1,000 tests
Device stores up to 2,000 results — retrievable via app or USB
Built-in PIN: no one modifies the device without authorisation
Alarm limit configurable: 0.020 – 0.100 %BAC in 0.010 increments
