# Henan Weiguo Intelligent Technology Launches AT319V Coin-Operated Alcohol Tester: Precision and Convenience for Multi-Scene Alcohol Detection Henan Weiguo Intelligent Technology Co., Ltd., a leading enterprise in the intelligent safety and environmental monitoring sector, is proud to launch the AT319V Coin-Operated Alcohol Tester—an innovative and high-performance device engineered for accurate human alcohol concentration detection. Equipped with an advanced fuel cell alcohol sensor, the AT319V sets a new standard for sensitivity, repeatability and ease of use, making it an ideal solution for a wide range of scenarios including bars, factories, workplaces, and public service areas. ## Cutting-Edge Technology for Unmatched Accuracy At the core of the AT319V lies a premium fuel cell alcohol sensor, delivering exceptional detection performance with a **test range of 0.000~4.000g/L** (supporting multiple units including mg/L, mg/100mL, %BAC, ‰BAC) and a high resolution of 0.002g/L. Boasting an accuracy of ±0.005% at 0.05%BAC, the tester ensures highly reliable and precise readings, a critical factor for alcohol safety detection. The device features a preset warning level of 0.180g/L and a danger level of 0.500g/L; once the alcohol content exceeds these thresholds, it immediately triggers audio and visual alerts via a 4-digit LCD screen and red/yellow/green indicator lights, providing clear and instant feedback for users. With a preheating time of ≤1 minute and a quick initialization process (only 6 seconds), the AT319V enables efficient testing even in high-traffic environments. Its robust design is built to withstand diverse working conditions, operating stably at a temperature range of 0℃~50℃ and relative humidity ≤95% (no fog), while the storage temperature can reach -20℃~60℃, ensuring adaptability to different climates and settings. ## User-Centric Design with Flexible Coin-Operated Functionality Tailored for practical on-site use, the AT319V integrates a humanized coin-operated system, offering unparalleled flexibility for operators. The number of coins required for a single test can be freely set from 0 to 15 via the internal dial switch S1 (1 coin as the default), and the device supports coins with a diameter of 15mm~29mm and thickness of 1.8mm~3.0mm, with a large coin storage capacity of 200 pieces. For customized coin setting, users can easily complete the calibration by inputting 20 different coin models, simulating real usage scenarios with fast and slow coin feeding speeds. The tester also features a user-friendly operation flow: after power-on initialization, the device prompts coin insertion and straw insertion via clear indicator lights. Users only need to insert the dedicated straw (straw box capacity: 200pcs, outer diameter ~7mm) and blow continuously and evenly— the device will issue real-time prompts for improper blowing, ensuring standardized testing. After the test, the alcohol concentration result is clearly displayed on the LCD screen and remains for several seconds before returning to standby, enabling continuous testing for high efficiency. ## Easy Installation, Maintenance and Durability Designed for hassle-free deployment, the AT319V supports two installation methods: wall-mounting (using the accompanying bolts) and desktop placement, with a compact dimension of 250mm×105mm×400mm and a net weight of only about 4kg, saving space and facilitating installation. The device’s working voltage is compatible with AC100V~240V (50/60HZ) with a DC12V/1.5A output, adapting to global power supply standards and making it suitable for international markets. Maintenance is made simple with the AT319V’s modular design. The fuel cell sensor has a long service life of over 2 years under normal conditions, and each sensor module can be used up to 1000 times. When the screen flashes “0000”, users can replace the sensor module without professional calibration—just remove the front panel, disconnect the pipeline, unscrew the old module and install a new one, reducing maintenance costs and downtime. The device also lists common fault solutions (e.g., reinserting the power cord for no LCD display, clearing blockages for gas detection failure), further enhancing usability. ## Reliable Performance with Strict Usage Guidelines To ensure long-term stable operation and accurate detection, the AT319V adheres to strict usage and maintenance standards: avoid dropping or strong impact; keep away from high-concentration interfering gases and corrosive gases (e.g., chlorine); wait 15 minutes after drinking for testing to ensure authentic results; and retry several times for the first test after long-term storage. These guidelines effectively protect the sensor and extend the device’s service life, ensuring consistent performance over time. ## Ideal for Global Multi-Scene Applications Compliant with international testing standards, the AT319V is a versatile alcohol detection solution for various global scenarios. It is widely applicable to entertainment venues such as bars and nightclubs for customer safety testing, factories and construction sites for pre-work alcohol screening, and public service areas for on-site alcohol detection. Its coin-operated design, accurate detection, and easy maintenance make it a cost-effective choice for both commercial and industrial users. As a core enterprise under Hanwei Technology Group, Henan Weiguo Intelligent Technology has always been committed to innovating intelligent safety monitoring products. The launch of the AT319V Coin-Operated Alcohol Tester reflects the company’s R&D strength and market-oriented design philosophy, providing a reliable and efficient alcohol detection tool for global customers and contributing to the construction of a safer working and living environment. **About Henan Weiguo Intelligent Technology Co., Ltd.** Founded in 2017 with a registered capital of 50 million RMB, Henan Weiguo Intelligent Technology Co., Ltd. is a key pillar enterprise of Hanwei Technology Group (Stock Code: 300007) in the field of home environment safety and health.
