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.
