Portable Personal Breathalyser with High-Precision Sensor and Safety Alarms

This handheld alcohol tester offers a practical method for checking blood alcohol concentration (BAC) levels at home, before driving, or in other personal safety scenarios. Its compact, pen-type design fits easily into a pocket, while the high-sensitivity semiconductor sensor provides rapid measurement across three common alcohol concentration units. The device is built for straightforward operation, featuring a clear digital LCD screen and an integrated alarm system that activates at predefined safety thresholds. With five included mouthpieces, it accommodates use by multiple individuals, making it a functional tool for households or small groups where responsible alcohol consumption monitoring is desired.

Features and Construction

The alcohol tester combines a precise sensing mechanism with user-focused functionality in a portable format. Its construction prioritises clear readouts and intuitive operation, supported by certified electronic components.

Material and Build

At the core of the device is a highly sensitive semiconductor alcohol sensor, designed to deliver accurate readings quickly through one of five blowing ports. The main housing, implied to be plastic, forms a slim, lightweight body measuring 124 × 80 × 35 mm and weighing just 93 grams. This pen-style build facilitates easy carrying and storage. The product complies with RoHS and CE standards, indicating adherence to specific European health, safety, and environmental protection directives for electronic goods.

Size and Practical Fit

With dimensions of 124 mm in length, 80 mm in width, and 35 mm in depth, the tester is deliberately compact. Its form factor is described as a 'pen type slim type' that fits into a breast pocket, emphasising its portability. The light 93-gram weight further enhances its suitability as a personal device that can be carried conveniently without adding significant bulk to a bag or jacket.

Uses and Placement

This breathalyser is designed for situations where an individual wishes to check their sobriety informally. Its applications span from personal curiosity to more defined safety checks, particularly before operating a vehicle.

Event or Professional Use

While primarily for personal use, the device could serve in settings where informal alcohol monitoring is helpful, such as at social gatherings or workplace events where individuals need to self-assess fitness to drive. The inclusion of five mouthpieces allows several people to use the tester sequentially. The audible and visual alarm provides an unambiguous warning when readings hit 0.05% BAC (or equivalent in other units), acting as a prompt against driving or operating machinery.

Everyday Home Use

For home settings, the tester offers a straightforward way to check alcohol levels after consumption. Its portability means it can be stored in a drawer or carried in a bag for use when needed. The clear LCD screen, which remains legible at night, and the simple three-step operation (install mouthpiece, press button, blow) make it accessible for occasional use without specialist training.

Benefits and Buying Value

The value of this product lies in its combination of precise measurement, clear safety prompts, and practical, reusable design. It provides a tangible tool for making informed decisions about alcohol consumption.

Reuse and Low Maintenance

The device is designed for repeated use. It is powered by standard batteries (not included), with one battery installation supporting approximately 200 tests. The automatic sleep function activates after five minutes of inactivity, preventing battery drain if the power is left on. The five supplied mouthpieces are replaceable, allowing multiple users or successive tests while maintaining hygiene. No complex cleaning routines are specified, suggesting low ongoing maintenance.

Why Choose This Product

This alcohol tester is a suitable choice for individuals seeking a portable, personal device for checking blood alcohol levels. Its key differentiators are the high-precision semiconductor sensor for accuracy, the multi-format display (%, ‰, mg/L), and the integrated audible/visual alarm that activates at safety thresholds. The compact size and included mouthpieces add practical value for household or small-group use. It operates effectively within a broad environmental range (-10°C to 50°C, up to 95% humidity), making it reliable in various conditions.
