Breathalyzers - Semi-conductor tech. ^
Semiconductor technology alcohol breath testers, also known as semiconductor breathalyzers, utilize a semiconductor oxide sensor to estimate breath alcohol concentration. These testers work by measuring the electrical resistance change in the sensor when alcohol is present. Semiconductor breathalyzers are compact, affordable, and widely available for personal use. They generally have shorter warm-up times and offer relatively quick response rates. However, compared to fuel cell breathalyzers, semiconductor-based testers may have slightly lower accuracy and precision. They typically have a limited detection range and display results in units such as % BAC, ‰ BAC, or mg/l. Semiconductor breath testers are suitable for estimating alcohol levels and promoting responsible drinking habits but may not be as reliable as professional-grade devices used for legal purposes. Regular calibration and adherence to the manufacturer's instructions are important for maintaining accuracy.
