Product Description:

The Real Instruments Portable Alcohol Tester Machine LCD Digital Display Breathalyzer Black, AT-21 also known as a breathalyzer or breath alcohol analyzer, is a portable and handheld device used to measure the alcohol concentration in an individual's breath. It plays a crucial role in ensuring safety on the roads and in various professional settings where sobriety is essential, such as law enforcement, workplace safety, and personal responsibility. The operation of an alcohol breath tester is based on the principle that when alcohol is consumed, it is absorbed into the bloodstream and subsequently exhaled through the breath. The device captures a breath sample and analyzes it to determine the alcohol content, typically expressed as Blood Alcohol Concentration (BAC) or alcohol percentage. Key features and functionalities of alcohol breath testers include: Accuracy: Modern breathalyzers are designed to provide accurate and reliable readings. They use advanced sensor technology, often employing fuel cell sensors or semiconductor sensors, to ensure precision in BAC measurements. Quick Results: Alcohol breath testers yield results within seconds, allowing law enforcement officers, employers, and individuals to make informed decisions swiftly. Portability: These devices are compact and easy to carry, making them suitable for roadside testing, sobriety checkpoints, and workplace testing. Many models can fit in a pocket or a glove compartment. User-Friendly Interface: Alcohol breath testers typically have straightforward user interfaces with clear displays, buttons, and indicators, making them easy to operate even by individuals without specialized training. Data Storage: Some models feature data storage capabilities, enabling users to record and store test results for later reference or reporting purposes. Calibration: Regular calibration is essential to maintain accuracy, and many breathalyzers allow for calibration checks to ensure proper functioning. Audible and Visual Alerts: To indicate the results, many alcohol breath testers feature audible alarms or visual signals, such as LED lights, to alert users to the presence of alcohol and the corresponding BAC level.
