AT319

Whether you’re managing a bar to remind patrons not to drive after drinking, overseeing a corporate fleet to ensure drivers are sober on duty, or running a driving school to maintain safe training standards—a precise, user-friendly, and durable breath alcohol tester is no longer a “nice-to-have” but a critical tool for modern safety management. Meet the AT319 Coin-Operated Breath Alcohol Tester: a game-changer designed with advanced tech, flexible settings, and hassle-free operation to make safety checks efficient and reliable, no matter the environment.

1. Core Strengths: Where Precision Meets Practicality

What sets the AT319 apart from ordinary testers? It solves key pain points of traditional devices by excelling in three critical areas: accuracy, flexibility, and usability.

Advanced Sensor Tech for Unwavering Reliability

At the heart of the AT319 lies a high-performance fuel cell alcohol sensor—the gold standard for breath alcohol testing. This sensor delivers exceptional sensitivity (catching even trace alcohol levels) and repeatability (minimizing discrepancies between tests), so you never have to second-guess results.
Official data confirms: At 0.05% BAC (Blood Alcohol Concentration), the tester achieves an accuracy of ±0.005%—far exceeding the error margins of basic models. When safety is on the line, this level of precision is non-negotiable.

Flexible Settings to Fit Any Need

No more compromising on “free vs. paid” or “unit compatibility”—the AT319 adapts to your scenario with customizable features:

Adjustable Coin Count (0–15 coins): Set to “0” for free testing (ideal for corporate fleet checks or in-house driver screenings) or 1–15 coins for paid services (perfect for bars, public venues). It comes pre-set to 1 coin, so you can start using it right out of the box.
Wide Coin Compatibility: Works with coins 15mm–29mm in diameter and 1.8mm–3.0mm thick—covering most common coin sizes globally, no special ordering required.
5 Selectable Units: Choose from mg/L, mg/100mL, g/L, %BAC, or ‰BAC via an internal dip switch (default: g/L). This ensures compliance with local standards, whether you’re in North America, Europe, or Asia.

Plus, it boasts a 200-coin capacity box and a 200-straw storage box—so you won’t waste time refilling supplies during peak hours (think busy bar nights or morning driver check-ins).

User-Friendly Design for Stress-Free Operation

You don’t need technical expertise to use the AT319—its intuitive design makes it accessible to everyone:

Compact & Versatile Installation: Measuring just 250mm×105mm×400mm and weighing only 4kg, it fits perfectly on a countertop or mounts to walls (includes bolts for easy installation). Perfect for tight spaces like bar 前台 s, guard booths, or driving school lobbies.
Clear Visual & Audible Cues: After powering on, LED lights and a buzzer guide users through every step (e.g., “Insert Coin,” “Insert Straw,” “Blow”). The LCD screen displays real-time info—like remaining coins needed or sensor test counts—so there’s no confusion.
Durable & Anti-Interference: Resists drops, strong shocks, and high-concentration interfering gases (e.g., smoke, fumes). It’s built to withstand daily use in busy environments.

2. Who Is the AT319 For? It’s Versatile Enough for Every Industry

The AT319 isn’t limited to “drunk driving checks”—it’s a multi-purpose tool that enhances safety across sectors:

Scenario	Key Need	How the AT319 Delivers
Bars & KTVs	Prevent drunk driving liability; offer paid safety checks	Coin-operated mode; disposable straws for hygiene; loud alarms for dangerous BAC levels.
Corporate Fleets (Logistics/Passenger Transport)	Ensure sober drivers; streamline pre-shift checks	Free (0-coin) mode; no extra cost for daily use; precise results to avoid accidents.
Driving Schools & DMVs	Maintain safe training; comply with regulatory standards	Wall-mountable; local unit settings (e.g., %BAC for the U.S.); clear results for instructors.
Public Venues (Stations/Ports)	Discourage intoxicated behavior; protect public safety	High coin capacity (200 coins); compact design for service desks; easy to monitor.

3. How to Use the AT319: 4 Simple Steps

Don’t let “tech” scare you—testing takes less than a minute, thanks to the AT319’s straightforward workflow:

Step 1: Power On & Initialize (≈6 Seconds)

Turn on the device. It will run a self-check: the buzzer beeps, LEDs flash in sequence (to verify functionality), and the LCD cycles through “coin count + unit” and “sensor test number.”
When the “Wait” light stops blinking and the “Insert Straw” light turns on, the tester is ready.

Step 2: Insert Coins (If Needed)

If set to “paid mode” (1–15 coins), insert coins while the “Insert Coin” LED flashes. The tester beeps once per coin and shows the remaining count on-screen.
When the correct number of coins is inserted, the “Insert Coin” light turns off, and the “Blow” light starts blinking.

Step 3: Take the Test

Grab a straw from the storage box and insert it into the tester.
Take a deep breath, then blow continuously and evenly until you hear a prompt tone. If you stop mid-blow, the tester beeps “di—di di” to remind you to restart.

Step 4: Read Results Instantly

The LCD screen displays the alcohol concentration immediately. LEDs and buzzers signal three result types—so you can act fast:

✅ OK (Below Warning Level): OK LED on; soft “di-di di” beep.
⚠️ Warning (Between Warning & Danger): Warning LED on; steady “di-di di” beep.
❌ Danger (At/Above Danger Level): Danger LED on; rapid “di-di di” beep—alert others to intervene.

4. Hassle-Free Maintenance: Fix Issues Fast, Replace Sensors Easily

The AT319 is designed to minimize downtime—even if problems arise, solutions are simple:

Troubleshooting Common Issues

Most minor faults can be fixed in minutes (no technician needed!):

Fault	Possible Cause	Solution
No LCD Display	Loose power cord	Reconnect the power cord firmly.
	Circuit malfunction	Contact your distributor for support.
No Response to Breath	Clogged gas inlet	Clean the gas inlet to remove blockages.
	Circuit malfunction	Contact your distributor for support.

Sensor Replacement: 3 Steps, No Calibration Needed

The sensor lasts over 2 years in standard use. When the LCD flashes “0000,” it’s time to replace the module—no special tools required:

Turn off the tester and open the front panel. Locate the gray sensor module (with a tube and connector).
Disconnect the tube and connector, then unscrew the module counterclockwise to remove it.
Screw in the new module clockwise, reconnect the tube and connector, and power on—you’re ready to test again!

5. Why Choose the AT319? 4 Unbeatable Reasons
