The ALC Smart Breath Alcohol Tester Digital LCD Breathalyzer with 5 Mouthpieces is a compact and reliable device engineered to estimate blood alcohol concentration (BAC) through breath analysis. Designed for both personal and professional use, it provides a quick, non-invasive method to assess alcohol levels, promoting responsible drinking and safe driving. The tester is equipped with an advanced flat-surfaced semiconductor oxide alcohol sensor, ensuring high sensitivity and rapid response times. Its digital LCD display with blue backlight offers clear visibility, even in low-light conditions, making it convenient for use at night or in dimly lit environments.

The device features a smart microcontroller unit (MCU) for precise control and consistent performance. It includes an audible alert system that warns users when BAC exceeds a pre-set limit (e.g., 0.05% BAC), enhancing safety by providing immediate feedback. The tester is powered by AAA batteries, with an energy-saving auto-shutdown feature that activates after inactivity to conserve power. Five replaceable mouthpieces are included, ensuring hygienic use for multiple users, making it suitable for family, friends, or workplace testing. Its portable, lightweight design with a keychain attachment allows for easy carrying, fitting comfortably in a pocket or purse.

The ALC Smart Breathalyzer is simple to operate: after a brief warm-up period, the user blows into the mouthpiece, and the device displays the BAC reading within seconds. It is designed for durability and ease of use, with a focus on health and safety, incorporating anti-return mouthpieces to prevent contamination. This tester is an essential tool for individuals seeking to monitor alcohol consumption responsibly or for organizations requiring preliminary alcohol screening.

2. Insert a mouthpiece into the designated port.

3. Press and hold the power button for 1–2 seconds to turn on the device. The LCD will display a countdown (15–20 seconds) during warm-up.

4. When the "Blow" symbol appears, take a deep breath and blow steadily into the mouthpiece for 3–5 seconds.

5. The BAC result will display on the LCD screen within 5–10 seconds.

6. If BAC exceeds 0.05%, an audible alarm and visual warning will activate.

7. The device automatically shuts off after 5–10 seconds of inactivity to save power.

Precautions

• Wait at least 20 minutes after consuming alcohol, eating, or smoking before testing to ensure accurate results.

• Do not blow smoke, food, or liquids into the mouthpiece, as this may damage the sensor.

• Perform multiple tests (2–5) at intervals of 3–5 minutes for best accuracy.

• Store in a dry, cool place away from extreme temperatures.

• Replace the sensor annually or after 500 tests for continued accuracy.
