ACE OF SWEDEN AF-33 Alcoolímetro digital cinzento-escuro, 0,00–5,00 ‰, ecrã LCD, sensor semicondutor, 2x AAA 107075

The ACE OF SWEDEN AF-33 stands out from typical breathalysers by combining a wide 0.00–5.00 ‰ measurement range with a clear digital LCD and a practical dark grey housing. Unlike basic single-use testers, this device uses a semiconductor sensor for repeatable readings and includes multiple mouthpieces, making it suitable for personal or shared use. The acoustic warning and low battery indicator add everyday convenience, while the automatic power-off preserves battery life between checks.

Highlights

• Wide measurement range: 0.00 to 5.00 ‰ (per mille)
• Digital LCD display for clear, immediate results
• Semiconductor sensor with typical accuracy ±0.1 ‰ at 0.5 ‰
• Acoustic warning signal when threshold is exceeded
• Auto power off and low battery indicator
• Includes multiple mouthpieces for hygienic sharing
• Compact dark grey design, powered by 2x AAA batteries

In daily use

The AF-33 is ready after a short warm-up of approximately 15–30 seconds and delivers a result in about 5 seconds. Simply attach a mouthpiece, blow steadily, and read the per mille value on the LCD. The device operates reliably between 5°C and 40°C, so it can be used in most indoor and outdoor conditions. When the battery runs low, the indicator reminds you to replace the two AAA cells, and the auto power-off function prevents unnecessary drain. For consistent accuracy, annual calibration is recommended.
