Alco-Sensor IV (ASIV)

The Alco‑Sensor IV is an evidential-grade, handheld breath alcohol tester from Intoximeters, renowned for its combination of simplicity, accuracy, and cost-effectiveness. Trusted globally across law enforcement, correctional, workplace, and maritime settings, the unit delivers fast, reliable BAC (breath alcohol concentration) readings using a rugged fuel-cell sensor that meets NHTSA (DOT) evidential standards.

Key Features & Highlights

• Fuel-cell sensor technology (electrochemical) with high selectivity—insensitive to acetone and other contaminants after standard deprivation.

• Evidential accuracy: ±0.005 at 0.100 g/210 L, meeting NHTSA/DOT requirements.

• Dual sampling modes:

  • Automatic deep-lung sample ensures accuracy.

  • Manual override for shy-lung or uncooperative subjects.

• Operator‐friendly LED display: provides step-by-step instructions; audio prompt supports clarity.

• 3‑digit BAC readout: easy to interpret results.

• Mouthpiece-activated power: insert mouthpiece to turn the device on/off; ejection feature prevents contact with the subject’s breath.

• Print & memory options:

  • Standard version stores the last test result.

  • Memory model stores ~1,080 results, exportable via optional printer or software like Total Recall or Alco-Sensor IV @ Work.

• Sturdy design: impact-resistant ABS composite with RF shielding; water-resistant case included.

• Portable & lightweight: 5.5″ × 3.5″ × 1.5″, ~0.69 lb with battery.

• Power options: runs on a single 9‑V battery (alkaline or rechargeable).

• Easily maintainable: user-replaceable mouthpieces ($0.40 each) .

• DOT-approved and CE marked—ideal for regulated testing environments.

• Optional software upgrades:

  • Alco‑Sensor IV @ Work: PC-based workflow for data logging, reporting, and printer interfaces in regulatory settings

The Alco‑Sensor IV sets the standard in handheld BAC testing—combining professional-grade accuracy, rugged portability, and user-friendly operation. Whether you're conducting roadside screening, workplace compliance, or maritime safety checks, this device delivers swift, reliable results with minimal training.

Its modular design allows you to upgrade with memory storage, printing options, or PC software as regulatory needs evolve—and all at a fraction of the price of more advanced evidential analyzers like the RBT IV.
