Household Alcohol Detection Instrument: Portable Breathalyser with Semiconductor Sensor and Warning Alarms

This compact, black alcohol detection instrument is designed for personal and household breath alcohol testing, offering a practical method for checking intoxication levels. Its core function is to provide a quick, breath-based measurement of alcohol concentration, displaying results clearly on a digital LCD screen that remains visible at night. The device is engineered for portability with a slim, pen-type design measuring 124 mm by 80 mm by 35 mm and a lightweight 93 g construction, allowing it to fit easily into a pocket. It operates on user-supplied batteries, delivering approximately 200 tests per set, and is suited for use before driving, for personal monitoring, or for mid-term checks at home, supported by its CE and RoHS certifications.

Features and Construction

The alcohol tester is built around a highly sensitive semiconductor sensor, which analyses breath samples to determine alcohol concentration. Its construction focuses on delivering accurate readings across a defined detection range while maintaining a user-friendly, portable form factor.

Material and Build

The device is housed in a black plastic casing that encloses the semiconductor sensor and electronic circuitry. The sensor is designed for rapid response and accuracy, measuring alcohol concentration in breath samples provided through the supplied disposable mouthpieces. The internal smart MCU (Microcontroller Unit) manages the measurement process, unit display switching, and the activation of warning alarms. The build quality adheres to standards reflected in its CE and RoHS certifications, indicating compliance with relevant European health, safety, and environmental directives.

Size and Practical Fit

With dimensions of 124 mm in length, 80 mm in width, and 35 mm in depth, the tester has a slim profile. Its 93 g weight contributes to its portability, making it easy to carry for on-the-go checks. The design includes a clear digital LCD screen for result readout and simple button controls for operation. The package includes five individual mouthpieces, facilitating hygienic use by multiple people or for multiple tests.

Uses and Placement

This instrument is intended for personal breath alcohol concentration testing. Its primary use cases revolve around safety awareness and personal responsibility in situations where alcohol consumption may impact judgement or ability.

Event or Professional Use

While designed for household use, the device can serve as a preliminary check in various settings. Individuals can use it for personal awareness before potentially driving, as a deterrent against drink-driving. It may also be utilised for informal checks at social gatherings or events to promote responsible drinking. The audio and visual warning alarms activate at specific thresholds (0.05% BAC, 0.50‰ BAC, 0.25 mg/L, or 50 mg/100ml), providing clear, immediate feedback when readings surpass these levels.

Everyday Home Use

For domestic settings, the tester offers a convenient way to monitor personal alcohol levels. Its portability means it can be stored discreetly and used as needed. The simple operation—installing a mouthpiece, a 15-second warm-up, and a short blow—makes it accessible for regular checks. The ability to switch display units between %, ‰, and mg/L, with memory of the last format used, accommodates user preference or regional standard familiarity.

Benefits and Buying Value

The value of this alcohol detection instrument lies in its specific functionality, portability, and included accessories, providing a self-contained tool for breath alcohol testing.

Reuse and Low Maintenance

The device is designed for repeated use with minimal upkeep. It is powered by standard 1.5V batteries (three required, not included), which provide an estimated 200 tests per set, offering good utility from a single battery change. The auto-sleep function conserves power by entering a low-power state after five minutes of inactivity, preventing battery drain if the power is left on. Maintenance is straightforward, limited to keeping the exterior clean with a dry cloth and ensuring the sensor area remains dry.

Why Choose This Product

This product provides a dedicated, portable solution for breath alcohol testing with clear, actionable feedback. Its key differentiators include the inclusion of five mouthpieces for multi-person or multi-test hygiene, the dual audio and visual warning system for high readings, and its compact, lightweight design for easy transport. The device delivers concrete measurements across three common units, operates within a wide temperature range (-10°C to 50°C), and performs reliably in environments with up to 95% relative humidity (non-condensing). For individuals seeking a practical, battery-powered breathalyser for personal or household use, this instrument offers these specified functionalities.
