Breathalyzer
Keywords: breathalyzer, AMT8100 breathalyzer, fuel cell breathalyzer, handheld alcohol tester, portable breathalyzer
Handheld fuel cell breathalyzer with a 1.44-inch LCD, Bluetooth printing and 2,000-record memory.
The AMT8100 is a handheld breath alcohol tester built around a new electrochemical fuel cell sensor. The sensor measures the alcohol concentration of the breath sample accurately and has strong anti-interference ability, so readings stay consistent in real roadside conditions rather than only on a test bench.
Operation is done from a keyboard panel on the front of the unit, with a 1.44-inch colour LCD showing the result, unit, temperature and time. A one-off anti-return mouthpiece protects each person tested, and results can be sent to the portable thermal printer over Bluetooth or uploaded to a computer for record keeping.

AMT8100 Fuel Cell Breathalyzer | AA Battery Handheld
1. Fuel Cell Sensor — accuracy and reliance from an electrochemical element with strong anti-interference ability.
2. Passive and Active Test — supports both active blowing and passive screening without a mouthpiece.
3. Adjustable Alarm Threshold — the alarm level can be adjusted to suit the local legal limit.
4. Anti-Backflow Mouthpiece — the one-off, one-way mouthpiece protects the health and safety of each person tested.
5. Colourful LCD — a 1.44-inch colour display shows the result clearly in daylight and at night.
6. Temperature and Time Indication — real temperature and clock are displayed with every reading.
7. Switchable Units — results in mg/L, g/L, %BAC or ‰BAC, and temperature in °C or °F.
8. 2,000 Test Records — the onboard memory stores up to 2,000 results for review.
9. Bluetooth Thermal Printing — a portable thermal printer connects over Bluetooth so results can be printed on the spot.
10. Password Management — settings and records are protected by a password.
11. AA Battery Power — runs on 2 × AA batteries, so a spare set can be carried instead of a charger.
12. Portable Body — compact handheld format for patrol cars, bags or belt carry.
