At-838 Alcohol Detector Breathalyzer – 0.000-0.199% BAC with 99% Accuracy for Drivers and Operators

The At-838 alcohol detector is a respiratory alcohol tester designed for individuals who need a straightforward, reliable way to check their breath alcohol concentration before operating a vehicle or machinery. With a measurement range of 0.000 to 0.199% BAC and a stated accuracy of 99%, this device offers a practical tool for personal or workplace use. It runs on two AAA alkaline batteries, features a 10-second preheating time, and delivers a reading in approximately 5 seconds. Its compact black design makes it easy to store and carry, providing a convenient option for quick alcohol screening.

Features and Construction

The At-838 is built around a semiconductor sensor that detects alcohol in the breath. Its simple interface and clear display make it accessible for anyone to use without extensive training. The device is powered by readily available AAA batteries, so it can be used on the move.

Material and Build

The unit is constructed from durable ABS plastic, a common material for handheld electronic testers. The black casing protects the internal sensor and electronics, while the mouthpiece area is designed for hygienic single-use or repeated use as per the user manual (not provided in detail).

Size and Practical Fit

Exact dimensions are not stated in the source text, but the device is handheld and lightweight, suitable for storage in a glovebox, tool kit, or security checkpoint drawer. Its compact nature means it can be deployed quickly when needed.

Uses and Placement

The At-838 is intended for drivers and operators of dangerous equipment, but it can also be used in any setting where a quick, non-invasive alcohol check is required. It is not a certified evidential device, so results should be considered as a screening indicator.

Event or Professional Use

In workplace environments, such as construction sites or transport depots, this detector can be used as part of a pre-shift check. Its 5-second reaction time allows multiple tests to be carried out quickly, helping to maintain safety protocols.

Everyday Home Use

At home, the device can be used by individuals who want to check their own alcohol level before driving. It provides a general indication of whether they are within a safe range, though it should not replace professional testing equipment.

Benefits and Buying Value

The At-838 offers a cost-effective way to carry out basic alcohol screening. Its battery operation, fast preheat, and quick reaction time mean it is always ready to use. While no long-term calibration schedule is provided, the device is a practical tool for ongoing personal monitoring.

Reuse and Low Maintenance

The detector runs on replaceable AAA batteries, so there is no need for charging cables. Regular use only requires changing batteries and keeping the sensor area clean. No specialist maintenance is needed beyond what the manual advises.

Why Choose This Product

If you need a simple, no-frills breathalyser for occasional or regular use, the At-838 delivers a clear BAC reading in seconds. Its 0.000-0.199% BAC range covers the typical thresholds relevant to driving limits in many jurisdictions, making it a sensible companion for responsible adults.
