Portable Breath Alcohol Tester with Digital Display and Audio-Visual Alarm for Personal Use

This compact alcohol detection instrument offers a straightforward method for estimating blood alcohol concentration (BAC) from a breath sample. Designed as a pen-slim, portable unit, it fits easily into a pocket and provides results on a backlit LCD screen in multiple common measurement units. The device is intended for personal awareness and household use, featuring a simple one-button operation, an included supply of mouthpieces, and an automatic alarm that activates at predefined legal or safety thresholds. Its operation is powered by user-supplied batteries, with a single installation supporting around 200 tests, and it enters a sleep state after five minutes of inactivity to prevent battery drain.

Features and Construction

The tester's core functionality is built around a semiconductor sensor designed for rapid response and a specific measurement range.

Material and Build

The main housing is constructed from plastic, forming a lightweight body that measures 124 mm by 80 mm by 35 mm. The design prioritises portability, with a form factor described as pen-slim to facilitate carrying in a shirt or jacket pocket. The unit's total weight is 93 grams, contributing to its easy transport. The product is certified to RoHS and CE standards, indicating compliance with specific EU health, safety, and environmental directives.

Size and Practical Fit

The physical dimensions of 124 x 80 x 35 mm define a handheld device. Its 93-gram weight ensures it adds minimal bulk when carried. The slim profile is a key differentiator, directly supporting its stated portability and discreet storage. The construction accommodates a standard button interface and a socket for attaching the supplied disposable mouthpieces.

Uses and Placement

The device serves as a tool for personal monitoring in scenarios where alcohol consumption is a factor, providing a digital estimate of impairment levels.

Event or Professional Use

While marketed for handy personal use, the inclusion of five mouthpieces suggests suitability for scenarios involving multiple individuals, such as social gatherings or small-scale workplace checks. The audio-visual alarm provides an unambiguous signal when readings exceed the programmed limits of 0.05% BAC, 0.50‰ BAC, 0.25 mg/L, or 50 mg/100ml, which can serve as a prompt for further action or decision-making regarding activities like driving.

Everyday Home Use

For individual household use, the tester offers a private means of self-checking after consuming alcohol. The process involves a 15-second warm-up, followed by a 2-3 second breath sample. The results, displayed on the LCD screen, are presented in a user-selectable format (%, ‰, or mg/L), and the device remembers the last selected format for convenience.

Benefits and Buying Value

The value of this product lies in its specific, measurable features that address the practical need for a portable, multi-user alcohol estimation tool.

Reuse and Low Maintenance

The device is designed for repeated use, supported by its battery-powered operation (batteries not included) which allows for approximately 200 tests per set. The automatic sleep function prevents accidental battery depletion if the power is left on. Maintenance is minimal, primarily involving the replacement of mouthpieces, of which five are supplied, and eventual battery changes.

Why Choose This Product

This tester provides a concrete set of specifications: a defined measurement range (0.00-0.19% BAC, etc.), a clear digital display, an integrated alarm at specific thresholds, and a genuinely portable form factor. It offers a packaged solution with necessary accessories (mouthpieces, manual) for immediate use. Its operation within an ambient temperature range of -10°C to 50°C and relative humidity up to 95% (non-condensing) supports use in various environments.
