What is the calibration basis for the alcohol detector?

According to the national metrological verification regulations and related industry standards, alcohol detectors usually need to be calibrated every 6 months. The setting of this cycle is mainly based on the following considerations:

Equipment stability: 

Over time, the sensors, circuits and other components inside the breathalyzer may have small performance changes due to environmental factors (such as temperature, humidity changes), wear and tear and other reasons, thus affecting the accuracy of the test results. Regular calibration can detect and correct these errors in time.

Regulatory requirements: 

Many countries and regions have clear regulatory requirements for the calibration cycle of alcohol detectors to ensure public safety, and calibration once every 6 months is one of the more common international standards.

Practical experience: 

Through long-term practical observation and data analysis, it is found that calibration every 6 months can better maintain the test accuracy of the alcohol testers and meet the needs of practical applications.
