Product details

The Testjezelf.nu Treebys CA05FS is a digital alcohol tester for personal use that allows for precise blood alcohol concentration measurements. This portable breath alcohol measuring device features a highly accurate electrochemical fuel cell sensor that delivers reliable results in the measurement range of 0.00 to 2.00 mg/L (0.00 to 0.95 BAC). The device offers short response times and typically displays measurements within 5-10 seconds after taking a breath sample. With compact dimensions of approximately 100 mm in height, 50 mm in width, and 20 mm in depth, as well as a weight of around 150 g, this alcohol tester is easy to transport for various situations. It features a clear digital LCD display that shows measurement results in both mg/L and BAC units, along with visual indicators for different levels of intoxication. The device operates on standard AAA batteries, allowing for about 300 tests per battery set, and has an automatic shut-off function to save energy. The mouthpiece is designed for hygienic single-use applications, with replacement mouthpieces available separately. The alcohol tester includes a calibration reminder function and requires professional recalibration approximately every 12 months or after 1,000 tests to maintain accuracy. It comes with a protective carrying case for storage and transport. This device is intended for personal informational purposes and should not be used for legal or medical decisions. Proper use includes waiting at least 15 minutes after consuming alcohol or using mouthwash before testing, as well as following the manufacturer's instructions for optimal accuracy. The digital alcohol tester provides a practical tool for individuals who wish to responsibly monitor their alcohol consumption.
