Digital Breathalyzers
Breathalyzers, also known as breathalyzers or breathalyzers,
are specialized measuring devices that determine a person's breath alcohol
content. These devices are crucial because breath alcohol content is closely
related to blood alcohol content, making them a reliable indicator of alcohol
consumption.
Types of breathalyzers
The breathalyzers available on the market differ mainly in
the type of sensors used. There are three main types of sensors:
Electrochemical sensors: these sensors are known for
their high accuracy and reliability. They react specifically to ethanol and are
therefore less susceptible to false readings from other substances.
Infrared sensors (evential measurement): These
sensors use infrared radiation to measure the alcohol content in the breath +
additional electrochemical sensors. They are extremely accurate and are often
used in government applications.
Semiconductor sensors: These sensors are less
expensive and are often used in low-cost devices. However, they are less
accurate and can be affected by other substances in the breath.
Calibration and maintenance
Regardless of the type of sensor used, it is essential for
all breathalyzers to be calibrated regularly to ensure measurement accuracy.
Calibration should generally be carried out every 6 to 12 months. This ensures
that the devices deliver precise and reliable results.
Conclusion:
Breathalyzers are essential tools for determining breath
alcohol content and contribute to safety on the road and in other areas.
Choosing the right device depends on specific requirements and budget, with
regular calibration crucial for long-term accuracy.
