It measures blood alcohol concentration (BAC) across a range from 0.000% to 0.199%, providing a quantitative reading to inform decision-making. The unit is specified to operate with 99% measurement accuracy and delivers this reading within a 5-second reaction time after an initial 10-second preheating cycle. Power is supplied by two commonly available AAA alkaline batteries, generating 3V DC for fully portable operation without the need for a mains connection. This combination of features makes it a practical tool for self-assessment in various settings.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black At-838 handheld personal alcohol breathalyser device.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/848\/2025-10-02\/original-image\/1715225160114.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe At-838 incorporates several defined functional specifications that determine its operation and use case. Its core purpose is the detection and measurement of alcohol concentration in exhaled breath, outputting a BAC percentage value.\u003c\/p\u003e\n\u003ch3\u003eMeasurement Performance\u003c\/h3\u003e\n\u003cp\u003eThe device's primary function is to analyse breath samples and display a BAC value. Its measurement range is specified as 0.000% to 0.199% BAC, covering levels relevant to many drink-driving laws and workplace policies. The manufacturer states the measurement accuracy for this range is 99%. The operational sequence involves a mandatory 10-second preheating time to prepare the sensor, followed by a 5-second reaction time to process the sample and display the result. This total 15-second cycle from power-on to reading defines the speed of operation.\u003c\/p\u003e\n\u003ch3\u003ePower and Portability\u003c\/h3\u003e\n\u003cp\u003ePortability is enabled by the power system. The At-838 requires a 3V DC supply, which is provided by two standard AAA alkaline batteries. This common battery type supports use anywhere without reliance on fixed power outlets or charging cables. The simple battery compartment design facilitates quick battery replacement to maintain device readiness. No battery life expectancy or charge duration is stated in the source material.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black At-838 handheld personal alcohol breathalyser device.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/848\/2025-10-02\/original-image\/18012010089737.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe stated measurement object is drivers and other dangerous operators where alcohol consumption could impair performance and safety. This defines its primary application scenarios.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eFor professional contexts, the device can serve as a preliminary screening tool for workplaces with alcohol policies, particularly in transport, logistics, or industrial settings. Event organisers or security personnel might use it for voluntary checks at functions where alcohol is served. Its battery operation allows it to be used at vehicle checkpoints, site gates, or within event spaces without requiring access to mains power. The quantitative 0.000-0.199% BAC range provides a specific figure rather than a simple pass\/fail indicator.\u003c\/p\u003e\n\u003ch3\u003eEveryday Personal Use\u003c\/h3\u003e\n\u003cp\u003eFor individual drivers, the At-838 offers a personal means of self-assessment before getting behind the wheel after consuming alcohol. It can be kept in a vehicle's glove compartment or carried in a bag for use when needed. The black colour finish provides a neutral appearance. The simple two-button operation (implied by standard breathalyser use) and clear digital display are designed for straightforward user interaction without complex setup procedures.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black At-838 handheld personal alcohol breathalyser device.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/848\/2025-10-02\/original-image\/2105350367288.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe value of the At-838 stems from its defined technical specifications and the practical scenario it addresses. It provides a specific, measured output for a clear safety concern.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eThe device is designed for repeated use over time. Maintenance primarily involves replacing the two AAA alkaline batteries as needed, a low-cost and widely accessible consumable. No specialist cleaning fluids, mouthpiece replacements, or calibration schedules are mentioned in the source text, suggesting a straightforward ownership model. The construction appears aimed at durable handheld use, though specific material claims are not provided.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThe At-838 presents a combination of a wide measurement range (0.000-0.199% BAC), a high stated accuracy (99%), and a quick result time (5 seconds after preheat). For users seeking a portable, battery-powered breathalyser with quantified performance metrics, these figures offer a basis for comparison. Its designated use for drivers and dangerous operators aligns it directly with road safety and workplace compliance applications. The use of standard AAA batteries avoids the need for proprietary chargers or cables.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black At-838 handheld personal alcohol breathalyser device.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/848\/2025-10-02\/original-image\/7933237467958.webp\"\u003e\u003c\/div\u003e","brand":"7nuift-hg","offers":[{"title":"Black","offer_id":57746649514328,"sku":"CJXFZNZN01698-Black","price":23.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0880\/2589\/1160\/files\/7933237467958.webp?v=1784504379","url":"https:\/\/homeenjoy.uk\/products\/alcohol-detector-personal-breathalyser-for-drivers-with-0-000-0-199-bac-measurement-range-99-accuracy-5-second-reaction-time-powered-by-2-aaa-batteries-in-black","provider":"homeenjoy.uk","version":"1.0","type":"link"}
