Portable Alcohol Tester Breathalyser with Digital Display and Audio-Visual Warning Alarms

This personal alcohol detection instrument provides a straightforward method for checking blood alcohol concentration (BAC) levels at home or on the move. Designed as a compact, pen-type device, it fits neatly into a pocket for discreet portability. The unit delivers quick, digital readings on a clear LCD screen and is equipped with an alert system that activates when results exceed specific legal or safety thresholds. Supplied with five disposable mouthpieces, it facilitates hygienic use by multiple individuals, supporting responsible choices regarding activities such as driving after social events.

Features and Construction

This alcohol tester combines a sensitive detection sensor with user-focused functionality in a lightweight, portable format. Its construction prioritises straightforward operation and clear result delivery.

Material and Build

The device utilises a highly sensitive semiconductor alcohol sensor, which responds quickly to breath samples for measurement. The main housing, inferred from its description as a pen-type slim design, is lightweight for portability. The device is certified to RoHS and CE standards, indicating compliance with specific health, safety, and environmental directives. It operates within an environmental range of -10°C to 50°C and at relative humidity up to 95% (non-condensing), making it suitable for various indoor conditions.

Size and Practical Fit

With compact dimensions of 124 mm in length, 80 mm in width, and 35 mm in depth, and a weight of just 93 grams, the tester is designed for easy carrying. Its slim, pen-type profile allows it to slide into a shirt or jacket breast pocket, making it a practical item to have on hand for impromptu checks without being cumbersome or obvious.

Uses and Placement

The tester's design supports both personal monitoring and shared use in casual or household settings, providing a factual data point for decision-making.

Event or Professional Use

While not a professional-grade device, its functionality suits scenarios where a quick personal check is desired. The inclusion of five mouthpieces allows it to be used sequentially by different individuals at a gathering, promoting a shared approach to safety. The audio-visual alarm activates at 0.05% BAC, 0.50‰ BAC, 0.25 mg/L, or 50 mg/100ml, providing a clear, non-subjective warning that a threshold has been met.

Everyday Home Use

For personal use, the device offers a simple check: after a social drink, one can use it for a measured indication of impairment level. The digital LCD screen displays results in your choice of units (%, ‰, mg/L), which the device remembers from your last setting. The screen's visibility at night adds to its practicality for evening or late-night use.

Benefits and Buying Value

The value of this product lies in its specific functionality, portability, and the practical support it offers for making informed choices.

Reuse and Low Maintenance

The device is designed for repeated use with minimal upkeep. It is powered by standard batteries (not included), which the source states can support up to 200 tests on a single charge. An automatic sleep function activates after five minutes of non-operation, preventing battery drain if the power switch is left on. Maintenance primarily involves ensuring a clean mouthpiece is used for each test and replacing batteries as needed.

Why Choose This Product

This alcohol tester provides a concrete tool for self-assessment. Its key differentiators are the combination of a portable, pocket-sized design with multiple measurement units and a clear warning system. The supplied mouthpieces enable hygienic shared use, and the device handles the measurement process automatically after a simple button press and breath sample. It delivers a specific, numerical result rather than a vague indication, contributing to more informed personal responsibility.
