How to use digital alcohol testers correctly to improve accuracy

Digital alcohol testers are a common tool used to measure alcohol concentration in the human body. However, many people do not understand the correct operating steps when using this device, which affects the accuracy of the test results. This article will introduce some key steps to help you use digital alcohol testers correctly, thereby improving the accuracy of test results.

To use digital alcohol testers correctly, you first need to understand how it works. Most digital alcohol testers use fuel cell sensors or semiconductor sensors. Fuel cell sensors determine alcohol concentration by detecting the current generated by the reaction of alcohol in the breath with chemicals in the sensor, while semiconductor sensors determine concentration by detecting the change in resistance caused by alcohol gas. Understanding these principles helps users realize the sensitivity of the sensor to alcohol gas in the environment, thereby avoiding potential interference during use.

Before first use or after a long period of non-use, ensuring that the device has been fully warmed up and calibrated according to the manufacturer's instructions is a key step to ensure accuracy. Warming up is to ensure that the sensor reaches an operating temperature suitable for detection, while regular calibration is to compensate for the long-term drift of the device and ensure the accuracy of the test results.

The performance of digital alcohol testers may be affected by environmental factors such as temperature, humidity, and altitude. Before use, ensure that the device is used in an environment that meets its working conditions. In addition, avoid using the device in environments with strong odors or other volatile substances (such as perfume, tobacco smoke, cleaning agents, etc.), as these factors may affect the accuracy of the sensor.

Following the correct operating procedures is essential to ensure accuracy. This usually includes:

Cleaning: Before use, make sure your mouth is clean and avoid food residues, chewing gum, or tobacco residue that may affect the results.

Deep breath: Take a deep breath before use to reduce the concentration of alcohol gas in the lungs.

Tight fit: Make sure the device fits tightly to your lips during the test to avoid air leakage.

Smooth blowing: Blow smoothly and evenly, usually for 4 to 5 seconds according to the device instructions, avoid being too short or too long.

Avoid continuous testing in a short period of time. Because the sensor needs time to reset, continuous testing may result in false low readings. If you need to retest, you should wait for a period of time to allow the sensor to recover.

It is also important to keep the device properly maintained and stored. Follow the manufacturer's instructions for daily cleaning and storage, and avoid extreme temperatures or humidity environments. This can reduce device aging or damage, extend its service life, and ensure test accuracy.

Finally, users need to be aware of some limitations of digital alcohol testers. For example, having just consumed alcoholic food or drinks, or having health problems (such as diabetes, gastroesophageal reflux, etc.) may affect the test results. In this case, the test results may require additional verification.

The correct use of digital alcohol testers is key to ensuring their accuracy and reliability. Through the above measures, users can effectively improve the accuracy of test results and make safer and more responsible decisions. At the same time, this will also help increase the public's trust in digital alcohol testers as an important tool to prevent drunk driving.
