Zhengzhou, China – November 10, 2025 – Henan Weiguo Intelligent Technology Co., Ltd., a pioneering force in smart safety and intelligent detection solutions, is proud to announce the global launch of its latest innovation — the **AT319V Coin-Operated Alcohol Tester. Engineered with precision, durability, and user-centric design, the AT319V sets a new standard for reliable breath alcohol testing in industrial,transportation, and public safety applications.
As part of its mission to enhance workplace safety and promote responsible behavior, Henan Weiguo introduces this advanced alcohol detection system to international markets through its official independent website and global distribution network. The AT319V combines cutting-edge fuel cell sensor technology** with robust construction and intuitive operation, making it an ideal choice for fleets, factories, law enforcement agencies, and public venues.
Advanced Technology for Accurate & Reliable Results
At the heart of the AT319V is a **high-sensitivity fuel cell alcohol sensor**, delivering exceptional accuracy, stability, and repeatability. With a wide measurement range of **0.000–4.000 g/L** (equivalent to 0–0.400% BAC), and a resolution of **0.002 g/L**, the device ensures precise detection even at low alcohol concentrations. Its **±0.005% BAC accuracy at 0.05% BAC** guarantees reliable performance under real-world conditions.
Key Features:
- Fast warm-up time : ≤1 minute
- Adjustable alarm thresholds: Warning at 0.180 g/L; Danger at 0.500 g/L
- Multiple unit display options: mg/L, mg/100mL, g/L, %BAC, ‰BAC (freely selectable via internal DIP switches)
- Operating environment: 0°C to 50°C, ≤95% RH (non-condensing)
- Power input**: AC100V–240V, 50/60Hz; Output: DC12V/1.5A
- Compact dimensions: 250mm × 105mm × 400mm; Weight: ~4kg
Flexible & User-Friendly Operation
Designed for versatility, the AT319V supports **configurable coin operation**, allowing operators to set the number of coins required per test from **0 to 15** using internal DIP switch S1. The device accommodates coins from **15mm to 29mm in diameter and 1.8mm to 3.0mm in thickness**, making it adaptable to various regional currencies.
To ensure accurate coin recognition, users can enter **coin model training mode** by inserting 20 different coins (recommended with varying years and speeds), optimizing performance in diverse environments. A built-in **straw compartment (200 pcs capacity)** and **coin return button** enhance hygiene and user convenience.
### **Simple, Step-by-Step Testing Procedure**
The AT319V guides users through a clear, intuitive testing process:
1. **Power On & Initialization**: Upon startup, the system performs a self-check, displaying "aa b" and "ecce" on the LCD. Once preheating is complete (~6 seconds), the “Wait” light blinks, followed by prompts to insert a straw or coin.
2. **Coin Insertion (if required)**: The LED flashes, and the device emits a “di” sound for each coin. The screen shows remaining coins needed.
3. **Breath Sample Collection**: After inserting a straw, users are prompted to blow steadily until a beep confirms completion. If breathing stops mid-test, a “di----didi” alert reminds the user to continue.
4. **Result Display**: Results appear instantly on the **4-digit LCD screen**, accompanied by color-coded LED indicators (Green/OK, Yellow/Warning, Red/Danger) and audio alerts:
- **OK (below warning level)**: Soft "di-di-di" sound
- **Warning (between warning and danger)**: Continuous warning tone
- **Danger (at or above danger level)**: Urgent beeping
Results are displayed briefly before returning to standby mode for the next test.
**Maintenance & Troubleshooting Made Easy**
Henan Weiguo prioritizes long-term reliability and ease of maintenance:
- **Sensor Replacement**: When the sensor nears end-of-life (typically after **1,000 tests** or **2 years** under normal conditions), the device displays a flashing "0000". The sensor module can be quickly replaced without calibration — simply open the front panel, unscrew the old unit, and install the new one.
- **Common Issues & Solutions**:
- *No LCD display*: Check power connection or contact distributor.
- *No gas detected*: Clear blockage in gas inlet or inspect for circuit issues.
### **Important Usage Guidelines for Optimal Performance**
To ensure accuracy and extend device life, Henan Weiguo provides clear user guidance:
1. **Wait 15 minutes after drinking** before testing to ensure reliable results and protect the sensor.
2. **Avoid high concentrations of interfering gases** (e.g., cigarette smoke, solvents), which may affect sensor performance.
3. **Do not inhale cigarette smoke directly into the detector**.
4. **Use only compatible accessories and matching coins**.
5. **Avoid dropping or subjecting the device to strong impacts**.
6. **If stored for extended periods**, the first test may be inaccurate — perform multiple tests to recalibrate.
7. **Store in a dry, corrosion-free environment** — avoid exposure to chlorine or other corrosive gases.
Global Readiness & Support
The AT319V is designed for international deployment, with universal voltage support (AC100V–240V) and multi-unit display options to meet regional regulatory requirements. Henan Weiguo offers **OEM/ODM services**, bulk shipping, and technical support for global partners.
Available now on the **official Henan Weiguo Intelligent Technology website**, the AT319V comes with a **1-year warranty**, fast delivery from stock, and professional customer service in multiple languages.
