This At-838 alcohol detector is a portable breath testing device designed for drivers and machine operators who need a fast, reliable indication of their blood alcohol concentration. With a measurement range of 0.000 to 0.199% BAC and stated accuracy of 99%, it offers a straightforward way to check personal sobriety before operating a vehicle or machinery. The device uses 2 AAA alkaline batteries for power, preheats in just 10 seconds, and provides a result within 5 seconds – making it quick to use in a roadside or workplace setting. Its black finish is discreet, and the compact size means it can be stored easily in a car glovebox or toolbox. Please note that this is a personal screening tool and not a certified evidential device.

Features and Construction

The At-838 is built around a simple semiconductor sensor that measures breath alcohol concentration. Its straightforward design focuses on ease of use for personal checking.

Measurement Range and Accuracy

The device displays readings from 0.000 to 0.199% BAC, covering typical legal limits in many jurisdictions. The manufacturer claims 99% accuracy, though in practice accuracy depends on proper use, battery condition, and environmental factors. It provides a quick numerical result without additional pass/fail indicators.

Power and Operation

Power is supplied by two AAA alkaline batteries (not included in the package). The preheating time of 10 seconds is short enough that you can begin testing almost immediately after turning the unit on. The reaction time of 5 seconds means you get a reading rapidly after blowing into the mouthpiece.

Uses and Placement

This alcohol detector is aimed at individual drivers, fleet operators, and workplace safety supervisors who want a preliminary check before driving or operating dangerous machinery.

Personal Driver Screening

Keep it in your car to test yourself or a colleague before setting off. The fast preheat and reaction times mean it can be used quickly, even in cold weather if the batteries are fresh. It is not a legal evidential device but can serve as a useful personal check.

Workplace and Commercial Use

Companies with safety policies around alcohol use can use this detector for on-site pre-shift checks. Its low power draw from AAA batteries makes it practical for mobile use. The black casing is unobtrusive and professional in appearance.

Benefits and Buying Value

For a simple, battery-powered breathalyser, the At-838 offers a practical way to screen for alcohol before driving.

Battery Life and Reuse

Because it runs on standard AAA alkaline cells, replacement is easy and inexpensive. The device itself can be reused many times as long as the batteries are kept fresh and the sensor is kept clean. No special charging cables are needed.

Why Choose This Product

If you need a straightforward, no-frills breath alcohol screening tool for personal use, the At-838 provides a clear numerical reading within seconds. Its 0.000-0.199% BAC range covers the most common legal limits, and the 99% accuracy claim gives a reasonable level of confidence for personal checking. Its compact black design fits easily into a glovebox or bag.
