Digital Alcohol Breath Tester with LCD Display and Key Chain

This digital alcohol breath tester is a compact device for estimating blood alcohol content from a breath sample. It uses semiconductor alcohol sensing technology and presents results on an LCD screen that indicates safe, warning, or danger status. The unit measures 110 x 70 x 25 mm and comes in black. It requires two AAA alkaline batteries, which are not included. Four nozzles are supplied. The measurement range is 0.00–0.19% BAC and 0.0–1.9 g/l, with accuracy stated as 0.01% BAC. The key chain attachment allows the tester to be carried on a keyring or stored in a small bag. Automatic shutdown helps reduce unnecessary battery drain. This product provides an estimate only and is not a substitute for a certified breathalyser or professional assessment.

Features and Construction

The tester combines a semiconductor sensor with an LCD readout and a key chain fitting. Its construction is described only in terms of colour, size, and battery requirement. The following sections cover what is known from the source text and avoid assumptions about materials or internal components.

Material and Build

The source text states the colour as black and gives dimensions of 110 x 70 x 25 mm. No body material, nozzle material, or weight is specified. The device has a key chain for carrying. It runs on two AAA alkaline batteries, which are not included. Automatic shutdown is a stated function. Because material details are not provided, no claims can be made about impact resistance, surface finish, or construction beyond the listed colour and size.

Size and Practical Fit

At 110 x 70 x 25 mm, the tester is small enough to fit in a pocket, glovebox, or bag. The key chain adds a carrying option for keys or a lanyard. The LCD display is part of the unit and shows the result categories. The device accepts four supplied nozzles, which are intended for breath sampling. No case or pouch is mentioned in the source text, so storage is limited to the device itself and the included nozzles.

Uses and Placement

This breath tester is intended for personal estimation of blood alcohol content. It can be used before driving or operating equipment as a rough guide, but it is not a certified enforcement device. The key chain and compact size suit keeping it in a vehicle, bag, or at home. The following sections describe practical scenarios supported by the product's stated features.

Event or Professional Use

At events or gatherings where alcohol is served, the tester can provide a quick BAC estimate. The LCD shows safe, warning, or danger based on thresholds: safe below 0.02% BAC, warning between 0.02% and 0.05% BAC, and danger at 0.05% BAC or above. The semiconductor sensor collects breath samples rapidly. Four nozzles are included, which may help with multiple users, though the source text does not state whether nozzles are reusable or single-use. No professional certification or calibration schedule is provided.

Everyday Home Use

For personal use at home, the tester can be kept in a drawer or on a keyring. It requires two AAA alkaline batteries, so battery replacement is straightforward. Automatic shutdown helps avoid leaving the device on. The black body and 110 x 70 x 25 mm size make it unobtrusive. Results are estimates and should not be used as the sole basis for deciding whether to drive. The source text does not include a carrying case or cleaning instructions, so only the supplied nozzles and device are covered.

Benefits and Buying Value

The main benefits supported by the source text are rapid breath sampling, a clear LCD status display, a compact key chain design, and automatic shutdown. The device offers a stated BAC range and accuracy figure. Four nozzles are included. No pricing, warranty, or longevity claims are provided, so value is described only in terms of these practical features.

Reuse and Low Maintenance

The tester runs on two AAA alkaline batteries, which are widely available. Automatic shutdown helps conserve battery life. Four nozzles are supplied, but the source text does not state whether they can be cleaned or reused. No cleaning solutions, replacement schedules, or storage temperatures are given. Maintenance is therefore limited to battery replacement and keeping the device dry and free from physical damage. No performance data is provided for repeated use over time.

Why Choose This Product

This product may suit buyers who want a portable BAC estimate with a clear LCD readout and a key chain fitting. It offers a stated range of 0.00–0.19% BAC and 0.0–1.9 g/l, with accuracy of 0.01% BAC. The safe, warning, and danger indicators provide simple guidance. It includes four nozzles and requires two AAA batteries. No competitor comparisons, price claims, or certification details are supported by the source text. Buyers should treat readings as estimates only.
