Portable Breathalyser with Digital Display and Safety Alarms for Home and Personal Use

This personal alcohol tester provides a straightforward method to check blood alcohol content (BAC) levels using a breath sample. Designed for portability, the slim pen-style device fits easily into a pocket and offers quick results displayed on a clear digital LCD screen. It operates across a detection range of 0.00–0.19% BAC, 0.00–0.99 mg/L, and 0.00–199 mg/100 ml, with automatic audio and visual warnings when readings exceed safety thresholds. Suitable for use before driving, at social events, or for personal monitoring, the tester includes five disposable mouthpieces for hygienic multi-person testing.

Features and Construction

The breathalyser combines a compact physical design with practical electronic functions for reliable alcohol detection. Built around a semiconductor sensor, it provides accurate readings quickly, with results shown on a backlit digital display.

Material and Build

The device housing is constructed from plastic, creating a lightweight and durable exterior. Internally, a semiconductor alcohol sensor provides the detection capability, supported by an intelligent MCU (Microcontroller Unit) that processes the readings. The unit carries RoHS and CE certifications, indicating compliance with specific electrical safety and hazardous substance regulations. Power is supplied by user-provided batteries, which the manufacturer states can support approximately 200 tests per installation.

Size and Practical Fit

Measuring 124 mm in length, 80 mm in width, and 35 mm in depth, the tester has a slim, pen-like profile. Its weight of 93 grams enhances portability, allowing it to be carried discreetly in a breast pocket, jacket, or bag. The compact design does not compromise functionality, housing the sensor, display, and control buttons within its small frame. The operational temperature range is -10°C to 50°C, and it can function in environments with up to 95% relative humidity (non-condensing).

Uses and Placement

This alcohol tester is designed for personal responsibility checks in various settings, from home use to pre-driving verification. Its portability and simple operation make it suitable for individuals who wish to monitor their alcohol intake.

Event or Professional Use

The device can be used to check alcohol levels before driving, helping users make informed decisions about their fitness to operate a vehicle. In social or event settings, it allows individuals to monitor their consumption. The inclusion of five mouthpieces means several people can be tested hygienically in succession, such as within a group of friends or at a gathering. The clear digital readout provides an immediate, objective result.

Everyday Home Use

For personal monitoring at home, the tester offers a convenient way to check levels after consuming alcohol. The safety alarm function provides an extra layer of awareness by sounding an alert if readings exceed 0.05% BAC, 0.50‰ BAC, 0.25 mg/L, or 50 mg/100ml. Its battery-powered operation and sleep mode (activating after five minutes of non-use) make it low-maintenance for occasional use. The device is also suitable for mid-term checks during an evening.

Benefits and Buying Value

The value of this breathalyser lies in its practical design, clear functionality, and included accessories for immediate use. It provides a tangible tool for personal awareness without requiring complex setup.

Reuse and Low Maintenance

The device is designed for repeated use. The manufacturer specifies that one set of user-provided batteries can support around 200 tests. The automatic sleep function conserves battery life by powering down the unit after five minutes of inactivity, reducing the chance of battery drain if the power is left on. The five included mouthpieces allow for multiple tests before replacements are needed, and the plastic housing can be wiped clean as needed.

Why Choose This Product

This alcohol tester offers a specific combination of portability, clear digital results, and safety alarms. Its pen-style design makes it exceptionally easy to carry, while the multi-scale detection (BAC%, ‰, mg/L) provides flexibility in reading units. The immediate audio-visual warning for over-limit readings adds a practical safety feature. Compared to simply estimating impairment, it provides a measurable, objective check based on breath analysis.
