The PCE-ALC 10 alcohol tester is a portable instrument designed to quickly check blood alcohol concentration through breath analysis. It is suitable for personal checks, preventive inspections and general safety monitoring, for example after consuming alcoholic drinks, before driving, during events, business travel, company activities or situations where an immediate indication of possible alcohol content is important. Its compact structure and simple operation make it suitable for both personal use and professional environments where a practical and fast instrument is required.

The measuring range of the alcohol tester is 0.00 ... 0.400 % BAC, with 0.001 % BAC resolution and 0.015 % BAC accuracy. These values provide a clear and detailed numerical reading of the measured result. The value is shown on a 1.4 inch backlit colour LCD display, allowing immediate reading even in less favourable lighting conditions. The numerical result is supported by a practical traffic light display system that helps the user interpret the measured level quickly.

The traffic light system uses three colour thresholds: green below 0.020 % BAC, yellow between 0.020 % and 0.080 % BAC, and red from 0.080 % BAC. This visual indication is particularly useful because it allows a warning or possible limit exceedance condition to be recognised in a few moments. If a limit value is exceeded, the instrument also emits an additional acoustic signal, making the check more immediate and easier to understand even when the user is not continuously looking at the display.

The PCE-ALC 10 is designed to provide fast results: the measuring time is approximately 5 seconds, while the warm-up time is approximately 10 seconds. This speed is important for occasional checks, preventive checks before driving or company environments where several people may need to be tested in sequence. After a measurement with high alcohol concentration, the device automatically performs a brief reset in less than 10 seconds to prepare more efficiently for the next measurement.

Operation is simple: the user briefly blows into the device according to the instructions provided by the instrument. The voice assistant guides the user step by step through the measurement, reducing the risk of incorrect test execution. This function is especially useful for inexperienced users, occasional checks or situations where the instrument is used by different people. The language menu indicated includes English and English GB.

The internal memory can store up to 100 measured values. This function allows previous results to be retrieved, comparative checks to be carried out and a record of measurements to be maintained. In personal use it can be useful for monitoring values over time; in a company or organisational context it can support internal checks, always in compliance with procedures, applicable regulations and the privacy of the people involved.

The USB-C interface allows practical charging of the instrument. The internal lithium-ion battery has a voltage of 3.7 V and a capacity of 800 mAh, making the alcohol tester convenient to use on the move. Automatic switch-off after 115 seconds helps save energy and preserve battery life when the device is not in use. This is useful in daily operation because it reduces the risk of unnecessarily discharging the instrument after a check.

The compact dimensions of 126 x 62 x 25 mm and the weight of 118 g make the PCE-ALC 10 easy to carry in a bag, case, vehicle, glove compartment or control kit. Handling is one of its strengths, as it allows the user to always have a quick instrument available for an indicative alcohol check. The IP20 protection class makes it suitable for use in dry, controlled environments, avoiding exposure to excessive dust and humidity.

In practical applications, the alcohol tester can be used by private users who want to check themselves after dinner, a party or an event; by professionals who drive for work; by companies with personnel involved in transport, logistics or critical tasks; by safety managers who want to promote preventive behaviour; or by event organisers and accommodation facilities that want to provide an awareness tool. It should be considered as an indicative and preventive support, not as a substitute for official checks carried out by competent authorities.

To obtain a more reliable measurement, it is advisable to wait an appropriate time after the last alcohol intake and avoid testing immediately after drinking, smoking or using products that could temporarily alter breath content. Measurement should also be performed in an environment compatible with the indicated operating conditions, from -5 ... 40 °C and 0 ... 95% RH. Storage conditions are -20 ... 70 °C and 0 ... 95% RH. Correct storage helps keep the instrument in good operating condition.

The alcohol tester is not a dimensional measuring instrument and is not used to check heights, transmission clearances, form errors or geometry. Its specific function is to measure alcohol content in breath. However, in a professional and safety context, the measured value can affect risk prevention, responsible driving management, personnel safety and user awareness. A quick check can help avoid imprudent decisions and support more responsible behaviour.

The PCE-ALC 10 is therefore a practical solution for users looking for a compact, fast and easy-to-use alcohol tester with numerical indication, traffic light display, acoustic signal, voice assistant, internal memory and USB-C charging. The combination of fast results, readable display, rechargeable battery and manageable structure makes it suitable for personal and professional checks where an immediate and clear indication of the measured alcohol value is required.
